You play for yourself and those people who enjoy what you are doing. If or when no one else enjoys what you do, you will play for yourself.
Just as we all have different tastes in music we have opinions on what is acceptable to us.
What is the point of degrading other people ?
We all do it whether it's telling someone their guitar is ugly or telling someone they are too old to play in public.
I guess your thread really illustrates the folly in it. So you have accomplished something positive in spite of your comments.
