Here's a list of issues. The videos may have been removed by now as it's old and he got some blowback for it. I have seen the video with my own eyes. For clarity they were laughing about how the woman would be upset at them walking through home depot carrying assault rifles. She lost her child in Newtown and has become a advocate for gun regulations. So yes they are ideologically opposed to one another but maybe pick another target to laugh at.

I think a lot of the comments in that thread are conveniently ignoring that he's openly mocking a mother who's upset by open carry assault rifles because she lost her child in a school shooting. The organization named has a lot of people who lost their children to gun violence. I think a decent person would be capable of stopping for one second and think better about the target of their mockery.

Lots of gun rights advocates are perfectly capable of making their point without directly mocking victims of gun violence.
