You are severely misquoting.Like, on the day they certify the elections and try to seat the new House and/or Senate majority, he holds a "peaceful" rally and encourages people to "peacefully" march to the Capitol and "fight like hell" to stop the transfer of power?
What Trump said, per WaPo, is "I know that everyone here will soon be marching over to the Capitol building to peacefully and patriotically make your voices heard".
There is no "fight like hell" in that statement.
In a totally different context and part of the speech, he said (again from WaPo) °If you don't fight like hell, you're not going to have a country anymore."
The actual context, in a separate part of the speech, was "And again, most people would stand there at 9 o'clock in the evening and say I want to thank you very much, and they go off to some other life. But I said something's wrong here, something is really wrong, can have happened. And we fight. We fight like hell. And if you don't fight like hell, you're not going to have a country anymore. Our exciting adventures and boldest endeavors have not yet begun. My fellow Americans, for our movement, for our children, and for our beloved country."y
