You seem to have a problem differentiating fiction from reality. Luckily most people don't, and it's been proven countless times.

If Theron actually did that, good. I think we can all agree Penn has embarrassed himself enough on the subject.

Get help.

Also, you need to read more Superman comics.

According to this summary of polls, the governor's race in Texas is currently running Abbott: 48.7%, O'Rourke 38.7%.

According to this poll (from 2019, but I'm guessing attitudes probably have not changed much in the interim) 81% of Texas voters support background checks for all gun purchases.  68% of Texas voters support red flag laws.  59% support banning the sale of selected semi-automatic rifles. 

So there's a notable amount of Texans who support some types of sensible gun restrictions, but do not support O'Rourke.  And there's about 12% of voters who are apparently still undecided.  It stands to reason those undecided are independent or moderate voters, since I can't imagine a liberal being on the fence at this point.  These are the people that need to be won over if O'Rourke is going to win. 

So what might win them over?  I would think probably an approach like "Look, I'm a reasonable guy, and here's some reasonable ideas that would make Texas more safe.  Here's some ideas a majority of Texans agree upon."  Basically making the argument that "I'm not the extremist, Abbott is" on this particular issue.

Causing a scene at a news conference, expressing righteous indignation, and scolding people does not advance any of this.  To the contrary, it makes it easier for Abbott to paint O'Rourke as some sort of loose cannon radical.  Democrats have been chest beating, scolding, and expressing righteous indignation for the past 30 years, and it hasn't moved the needle on voters regarding this issue.

So much so that you'd vote against your principles?    

Seems naive to me. The change needed is much more profound.

But...sure.   Let's blame video games.  Let's shift the blame to an easy target.  As Michael Roberts has said in other threads, that deflects from the hard answer.  Japan, England, most of the free world has easy access to the same games and the same content but has none of the problems with guns as America has.  Wonder why?  Drill down (not too deep) and I think you'll have your answer and it's not video games. 

Point is, the only path to any semblance of a solution is to persuade people who support some form of gun control but vote Republican to instead vote Democratic in enough elections to make a difference.
