WHMP is probably the least right-wing commercial talk station left. The daytime lineup is local news, a local liberal host, Stephanie Miller, Thom Hartman and Clark Howard. They only added Dave Ramsey and Lars Larson (weekend) when the liberal talk offerings dwindled to near nothing.
WRSI never struck me as tilted towards a male audience, either. I'd guess its demos are pretty evenly split.
Lazer as alternative seemed a fit with the other properties - it took the alt stuff that was popular and didn't fit on WRSI, and also gave them a compliment to their Amherst/Northampton CHR on a "metro signal" (Hits 94.3.) Their stick is in Northampton, and was broadcast from there for years, originally as WHMP-FM which migrated from CHR to Alternative in the 90s then to Active.
But maybe the goal is to more closely compliment WAQY and aim at a male blue collar audience in and around Springfield.
