Why are introverts so frowned upon?

Okay, so I’m introvert. I’m not extremely shy or anything and it’s not like I avoid social attention at all costs. I’m really a nice guy (or at least in my opinion),I’m fairly friendly and I like making new friends. When it comes down to it, though, I’m not a huge socialite, I never need to be the life of the party and I’m definitely not a “people-pleaser”. I’m more comfortable with a handful of good friends than I am with a large web of good acquaintances. I give most people a fair chance but I’m very selective with who I let in 100%. I take time to open up and sometimes (or maybe a lot of the times), I just need my alone time.

I definitely see the merit to having a large network, but I dont understand why the term “introvert” carries such a negative connotation with it. It seems to imply that just because a person isn’t an expert at making new friends or doesn’t plaster themselves across town looking for new friends that they’re somehow “different” and should be avoided. Why is “extroverted” the inherent better or more preferred term?
