Barely saw this as it is not on my meme. We run out of thread in here sometimes. What you do is just find another comment in the thread from the user you want to reply to.
Anyhoo, not a huge deal.
If there are actually offensive memes you can flag them. However if it is only offensive because of a differing opinion I wouldn't. But I flag anything that is truly abusive. There were a few pedo memes I did flag some time back, and some that were calling for actual violence against others. And you knew it wasn't satire because of the one who was posting. But it is important to know that satire is big around here. Something may come off one way when was meant another.
