Hey, my dude, you are entitled to your opinions about my work, you are entitled to not like my work. I would perhaps suggest its kind of a "dick move" to reblog someone's stuff with rude comments. But hey it's Tumblr people can do that, personally, I have better things to do but to each their own.
I made my "gay mood" comic because I needed a break from working on a 6-page comic about the effects of sexual assault, sometimes I want to draw stuff that isn't about sad shit!
So again, if you want to be rude to strangers on the internet, who might make things because they are depressed and want to draw something fun and be relatable to others, that's your choice. But maybe you should find a more constructive way to feel better about yourself.
