A thing that a lot of people don't realise it that even if you don't like something, or you are not interested in a certain topic, it doesn't mean it can't have value to someone else.

But, since it is the internet, it is way easier to just hate and troll, than to actually create original content.
I can understand your frustration with this kind of behaviour, but you know, you have already achieved way more, than they will in their whole miserable life.
Just think "Fuck it", smile and walk away leaving the haters in the dust :)
