Let' point the finger at why we have all these illegal immigrants.....good, old Uncle Sam himself. How many South American countries did we go into back in the 40s/50s/60s and decided that their president/prime minister/legislative people had to go because it seemed like they were leaning towards socialism or communism? So what if their citizens voted for them and THAT'S what they wanted? As long as OUR people were in charge and did what WE said, no problem, no matter how brutal they were to their own citizens. Can't have another Cuba in our backyard. So what if it "inconvenienced" the citizens of said country. Of course it's gonna lead to the rise of narco terrorists and people looking to survive however they can which includes fleeing to another country were they hope they can survive and not worry about being killed just walking out the front door. But things seem to be swinging back to the "bad" old days in some of those countries.
Have you ever lived in one of those South American countries? I have and ran radio stations in several of them and programmed in almost all of them. And the situation there is nothing like what you describe.
And as a second aside, what if one of their high payin' advertisers decided to come to whatever station is running these Homeland ads and say "You know what? We don't agree with those ads and don't want to be associated with a station that runs them. So we're going to take our high five or six figure advertising budget elsewhere." The stations are going to be stuck between a rock and a hard place. Good luck telling Homeland Insecurity that "we're not running your ads anymore." the only way around it I could see is if the government re-classifies it as a PSA and told them they have to run it. Either way, I bet the FCC is knocking on their door10 minutes after they tell the government to get lost.
Stations are not required to run specific PSAs. For example, at talk and sports KTNQ when I was PD, we only ran local PSAs for very local entities, like church car washes or a school soccer team fund raiser; they were done live by the talk hosts and were not scripted. We never ran government or even Ad Council PSAs.
But, as far as paid advertisements, the FCC only regulates "Lowest Unit Rate" for specific campaigns during a specific campaign period. All the rest are just "ads".
One of the things our communications attorneys send memos regularly about is the fact that stations can not take ads from some advertisers in a category and turn down others. The example I've used several times is the Puerto Rico (U.S.A.) broadcaster association amendment to its bylaws whereby we would take local rum ads but refuse other rums not from the Island and all other hard liquors.
Several of us presented this proposed bylaw to counsel, and we were rewarded with "don't even consider this... and if it is discussed in a meeting with other stations, excuse yourself by saying
'counsel told me it is not legal to discuss this'"
The issue is that you must take any and all ad buys in a category if you accept any individual one.
There are exceptions.
On my Beautiful Music station in San Juan years ago we turned down a few "loud" ads that did not fit the mood of the format; we offered to produce equivalent fitting ads ourselves. As we applied this to all loud ads, it was approved by counsel.
On the #1 and #3 stations in Puerto Rico, we put in quotas for each campaign. In each race, there was a maximum of spots that we'd run so as to not overload the format with all political ads. Ray Kraus of Koteen & Burt even ran this by the Commission informally and got an "appears upon review" to conform with rules pertaining to political advertising. We also excluded all PAC ads entirely, which was legal, too.
But if I had excluded the PNP candidate for Governor but taken the ads from the PPD one, we would have been in violation.
In this case, the "deport yourself" ads are simply commercials for a legislative or law enforcement cause or entity. If a station turned them down, they could not take other "cause" ads. One would have to consult counsel to determine if the causes could be highly specific or whether excluded buyers of time could file suit based on a restraint of trade; this is not an FCC issue but a commerce / trade one and would be an action against us by, for example, one of the agencies that regulates commerce, trade and business.
Examples of how stations are bound by other agencies beyond the FCC is the concern about running cannabis dispensary ads on radio and TV. The FCC does not prohibit such ads, and individual states may have legalized marijuana. But federal laws might put a station in danger. So, other than a station or two in Colorado, I don't believe any are running ads for "your local pot spot".
In the current environment, where the FCC "head" seems to envision regulation far beyond and much deeper than we have ever seen, if I were still managing stations I would definitely not want to provoke a very costly investigation by any of several possible federal agencies.
