I don't see how cutting them out creates a positive. It's like "Javy thinks men can become women", now I have one less person to play disc golf with.
What's the point of that? People can have different opinions, it's not their only character trait.
Similarly, people I dislike (rude or mean people, for example) make me unhappy when I'm around them. Cutting them out of my life is a net benefit there too, because I'm happier without them.
And maybe "How does this benefit me?" isn't the right question to be asking in this situation.
"Moderates" always like to speak in vague terms as if it's not literal murder being proposed by one side. I literally know a guy who is accumulating firearms, has bumper stickers that say "kill your local pedophile", and thinks all trans people are pedophiles. This is not a person I am going to be friends with just because we play the same kind of guitar music.
Quality over quantity for a start.
> people can have different opinions
Not every opinion deserves the same level of tolerance, respect or acceptance. If someone I know starts goose-stepping I’m not going to write it off a “just a difference in opinion.”
