It was a self-deprecating joke which back-fired because nuance is lost on the internet. You got triggered, which is entirely human, but at this point, you're the one who is doubling down. Perhaps it's a good time to disconnect and enjoy some time with your family.

I didn't "down" in the first place, but "no you" is typical of your ilk. Your comment is dishonest denial of your ageist bigotry, an inability to take responsibility for your actions. And I don't take life advice from trolls, bigots, and the like.

I won't respond further.
