Broadly speaking, I think that because TRAs have been telling everyone "shut up, it's not that bad, get over it" for so long, I think everyone is primed to react to any defensiveness with anger and hostility. I get the anger, the sentiment of, "No! I'm right to be angry!" And it is righteous anger, more or less.

But somehow, people take the step from there to actively feeding the anger. For example, I think that being angry at the actions of TRAs is enough. But some people want to drum up their anger even further by attributing malicious intent to them. The TRAs are bad enough as they are. There's absolutely no need to extrapolate, or draw conjecture you have no real evidence for.
