I agree. It doesn't make a difference. It's not like you'll change their mind. They aren't looking to learn about your side of it. They only want to prove you wrong. So you'll waste your time.

Discussion can be very productive.

because they want to be heard

Well, there's a difference between arguing with someone and debating with someone, in my eyes. Debating with someone is fine, and can actually be a lot of fun when personal insults aren't thrown around. But yeah, arguing with people isn't worth it.

To justify their view point is right. Finally arguments will be waste of time😆

i find most things arent worth the argument

Depends on the argument... Often, because it matters to THEM, but not always of course. Or they're drunk ;)

Because we are human and if nothing is "worth it" then there are bigger issues, in my humble opinion.

Because people disagree and some things actually are worth fighting for.
