You're pushing an extremist view that promotes age-based genocide, of course you should be removed from the platform.
If they're gonna police free speech, the least they can do is be consistent about it.
We are all getting older, we have elderly relatives who we love and aging is just an obvious part of life. In that context people won't take it personally and understand the nuance. I can bitch about boomers to my boomer parents without contradiction. And I don't get offended if the kids in my family call me an old person. It is funny because it is so universal.
Obviously that does not justify anything exactly and we should be respectful. But there is good sense in being generous and not taking offence.
