What do I do if people attack just for expressing an opinion?

Idk if I’m b coming an old lady in my thirties

But to me it just looks like when people gang up on me on Reddit for expressing an opinion they dislike, I’m like “y’all stupid”— it don’t make me change my view. Do ppl actually think that behavior makes someone change their opinion? Usually it’s not even something horrible like someone being racist it’s just a DIFFERENT OPINION. Or they just don’t like that I didn’t soften it with tons of cushioning.

Y’all just sound like whiny babies. You’re not convincing me I’m wrong to hold an opinion. It’s stupid.
