People at my school only find stupid reasons insulting the ORIGINAL 150. It makes me ashamed I even know them. To them it was just some fad a few years ago. They're all just sheep following the fads. In a few months to a few years and people who think they're still cool will get insulted for it. Point is people think what's cool based on what others think is cool.
I am about to go on a major rant so you may get bored.
Furthermore they don't think of new insults. (Except at my current school where a few look up new Pokemon and use that to their advantage.) They insult you and Pokemon there are 3 ways to counter it. 1. Ignore them. 2. Turn it back on them. 3. Insult them and if they get angry enough that they'll attack you and hopefully an authority figure will be nearby and deal with it.
Anyway they probably liked it at some point if they acknowledge that it exists. They just want to look cool in front of their peers. They do this for the same reason some people smoke and do other drugs, peer-pressure. There will always be jerks. Most people learn to deal with it. Some don't and they decide to keep it a secret. People say I have a problem because pokemon is a lot of my life, but I won't get into that.
