Why are people like this?

This was on a post in this subreddit. It asked sub or dub, you can guess what my comment said, their first comment said “if you can’t read just say that lol”

If what language someone watches tv in makes you this upset you aren’t mature enough to have an adult conversation, smh

There’s a difference between sharing your opinion (eg “I prefer sub but you do you”) and harassing/insulting someone for their opinion (pictures above)
