I am so with you on this. I, too, deactivated my Facebook account for exactly the same reason. I say nothing to anyone about my political views because I do not want to be called names.
I think what leftists did not understand is that for years people on the right have been silenced by their bullying tactics, and they were shocked to find out that we even exist.
Maybe this is their “extinction burst”.
When bullies are confronted and dealt with(or sometimes simply ignored)they often escalate for a time before backing down.
