A couple of takeaways:

Libs are arguing with people who (at least claim to) are very familiar with firearms and the safety. In threads about other shootings, they call gun owners knuckle draggers who are incapable of following rules. Here, the libs wrongly tell these people they are wrong and the "rules are different on a movie set"

What changed?

Also, they seem to be implying that it's ok to operate firearms with zero safety training. Imagine suggesting such a thing in a comments section about a school shooting.

Is this all because Baldwin got in Twitter fights with Trump?

Also, noticeably absent is any discussion about how this is largely a labor issue.
