It's not just that. Timelines are generally unavoidably toxic. It's not going to stop people from retweeting things and then shouting about it, or writing condescending, smug threads starting with "We need to talk about ...".
We need to talk about people who think the phrase 'we need to talk about...' is a fruitful way to start a conversation when "In my opinion" is probably more welcoming and conducive opening to a discussion that doesn't turn into ideological jousting right from the start.
