Why do some people find it hard to accept when other people have different perspectives, opinions, views, beliefs, viewpoint etc?

[Anonymous]

There are people in the world who will go out of their way to insult and criticise other people just for having a different opinion, perspective or view than their own.

If somebody holds a strong opinion and belief about something you likely cannot change their mind.

Many people don’t like it when other people try to force their belief onto them. You’re likely going to annoy people and make people dislike you if you try and force your beliefs into them. Don’t waste your time.

Well you're right according to multiple studies, just over 50% of people in regards to topics they find significant they won't change their mind even after being presented with evidence...
Why they push it, comes down to a simple principle of conviction, and the need to share that conviction with others.

A side note though (only sorta)
As with most significant topics (since they usually relate to tangible issues) there aren't really any opinions (since opinions aren't rooted in facts/logic)

There are only those using evidence/logic/reasoning, and those who are rejecting it (usually based on emotion)
Just keep that in mind, next time you feel like somebody is lecturing you; are they explaining a viewpoint (cuz even for things we may disagree with, there is still knowledge that can be gained)... or are they just complaining (these types don't usually persist super long though, I get bored of repeating the same bs pretty quickly)

I mean you are right it's mostly a waste of time. But it is to try help actually.

The ultimate reason is cause if I wasn't making sense I would want someone to tell me. Others don't want that though... They do like to be stuck in their illogical thinking.

But you never know I may find others that do want it pointed out. Or it makes another person see why I am right and they shouldn't agree with the views the other has.

Well that depends on what the views are. Most views say a lot about what kind of person someone is and people might not want to hang out or associate with a specific kind of person.
