I don't think the main worry should be about being harmed. Yes, we can all avoid taking it personally and being harmed. We do that by avoiding, by withdrawing, by not engaging. That is the real damage - it is no longer safe to discuss things. People talk about hyper-partisanship but a large part of this is that there are actors who are just in it for the lulz and people that have emotional problems in their lives who use political discussion as a way to exercise their personal anger.

Sure, we can personally stay safe, but public discourse cannot.
