While this post is talking about the internet, in general it is important to talk about “politics” with people (what is “political” ?).
If you don’t talk to people about why racism, sexism, transphobia or something else is bad, they will bring that conversation to people who don’t have the choice to ignore the conversation. They will harm and harass minorities.
I agree that the internet might not be the best place to change people’s minds, but it is important to name and argue against bigotry when encountered.
You should of course still be mindful of your own mental health <3
I can see where you come from, but as a gay man, I would go crazy if I had to enter every homophobic encounter with an open mind.
Also, entering an argument might not change the other persons mind, but it might change the mind of bystanders
