"the Rich" aren't some kind of homogenous block that all act and speak in unison. Putting people in groups like that really worries me.

It's curious that you didn't oppose "the poor" group, only "the Rich", with capital R.

Because it's much worse when you put people in a group and then attack that group than when you just group. "We need to help the poor", not very problematic. "The poor are lazy and deserve to suffer", very problematic.

You raised your shield to defend the people who have all of the resorces to defend themselves. Are you sure this is the best way to spend your time?

Yes, I don't want some communist revolution or othering or dehumanization which frequently is a precursor to violence. Are you sure criticizing how other people spend their time is the best use of yours?

Poor behavior by one party does not excuse bad behavior by another.
