Why are we not allowed to have our own opinion or view on something, without being yelled at or ridiculed for it?

Apparently some people's self-worth is so tied up with what they believe that they take any statement or question that challenges their own beliefs as an attack on themselves. That's the only explanation I can think of. Either that or they just resort to personal attacks because they can't refute someone else's argument. It's sad.

I've rarely had anyone yell at me for expressing an opinion. But I've been blocked a lot for it. Oh well. 🤷‍♀️
