They ban you if you make disparaging comments to another member. But they also ban you if you make disparaging comments about LGBT people.
They do not seem to care that leftists can call conservatives on ImgFlip, Nazis, fascists, racists or any other incorrect insult. They also don't seem to care if Christians are attacked.
So there is a real double standard here. If you speak ill of the liberal protected groups then into ImgFlip jail you go. If you speak ill of any group on the liberal hate list then you get to say whatever you want.
They once banned me because I quoted what Dan Ackroyd used to say to Jane Curtain on the Point/Counterpoint segment of the original cast of Saturday Night Live. I meant it jokingly but I got banned anyway.
