Is exposing a racist/bigots ethical if it could negatively impact their life?

I know I’m posting a lot of threads but this is something that’s been on my mind. For a while, I’ve been debating someone who has expressed some bigoted/borderline racist views(not White supremacist level) in their responses. As a result, I’ve been thinking about exposing them for this but there is a nag at the back of my mind that despite my distaste for this person, it could have consequences on their life. I once heard on how someone posted allegedly problematic drawings and nearly killed themselves due to the backlash they got and I don’t want to be responsible for something like that. So, is it ethical to expose bigots if has consequences on their lives.

Don;t know why there is a duplicate. Mods, please delete this thread.

Dude, they’re all duplicates.

These threads should all be polls. You are asking for opinions.

Oh, I didn’t know about that, sorry.

Should I make a poll thread then?

Many of your questions would be better answered by polling.

Just made a new poll.
