You're being extremely dismissive with that "too fucking bad" statement. You're part of a community, here and on other forums/places. It's not a simple matter of avoiding everything pony-related, because we can't, because it's all over the damn place and affects how people act both with each other and with other people. Although you apparently don't seem interested in an actual outside opinion on the matter, or considering how the behavior of your children's cartoon subculture/identity impacts those who don't share it.
Correct on all counts.
I've heard the arguments many times. I've heard the complaints many times.
I've heard it every time people complain about Starbucks being "everwhere."
I hear it when people complain about the latest song on the radio they don't like.
I hear it when people complain about the latest popular book or movie.
These things can be an eyesore (earsore). Memes and fads get annoying. Not everyone likes every piece of pop culture, and seeing it everywhere can be grating. I get that.
But I do not believe that hiding away one's passions and interests is necessitated by courtesy. In fact, I consider tolerating other's passions and interests, provided they're not actively (key word) shoving it down your throat, to be necessitated by courtesy. Who's the jackass here? The one screaming "hide what you like, and stop identifying with it, because I DON'T LIKE WHAT YOU LIKE."
Some things you will not like. Some of those things you will see often. Get over it, because insulting and trying to stifle those that do like it is simply rude.
We got a good fire here. Anyone bring the crackers yet?
