I don’t understand how even the people who might agree with you aren’t bored of seeing formulaic offtopic Trump bashing that could be produced by a script polluting every discussion they view on the web.
Assuming you were honestly looking for an explanation: not bored because they don't participate in the same discussions as you might, where the conversations turn to being "formulaic". In my world, and I assume in the world in which the OP lives, it's not immediately obvious why someone would run their mouth about things they know little about when an expert is standing right next to them.
