As someone who believes in Biblical Patriarchy, I guess that makes me a “Men’s Rights activist”. However I would in no way condone this man’s actions. Life is not fair, some men get the girls and other men don’t. You don’t have the right to take out your frustrations about not “getting any” by murdering women.
Contrary to popular belief in some feminist circles, you can believe in Patriarchy, or male dominance of society and still believe that women should still be treated with dignity and respect. Now there may some disagreement about what dignity and respect means, Biblically it does not mean equal freedom. It simply means not treating a human being like an animal, and not abusing them.
As far as the whining goes, there is enough of that to go around on both sides with men and women. If we are strictly talking about dating, men whine when they don’t get the nice looking girls, and women whine when men leave them for nicer looking women.
However Tangled then goes off the deep end by saying white men do most mass shootings because they think they are entitled.
So when a black man goes in a shoots up a party store, or does a drive by shooting he doesn’t feel entitled to do so?
She also makes the connection that to hate feminism (as MRAs do) means that all MRAs hate women. The reality there are extremist feminists and extremists MRAs that yes do spill utter hatred of the opposite sex, but that does mean all feminists are man haters or that all MRAs are woman haters.
Personally I hate feminism, but I do not hate women. I pity feminists (both male and female advocates of the ideology) and pity their young children who are often left without a mother to care for them.

The white male mass shooter connection is not my idea, I’ve seen a few articles about it, and I should have cited it. here’s one: http://www.rolereboot.org/culture-and-politics/details/2012-07-why-most-mass-murderers-are-privileged-white-men MRA’s may or may not hate women, but enough of their websites are filled with misogyny. Also since I’m an active and public feminist many men claiming to be MRA’s say things to me that go beyond rude to scary. Maybe those men hate me because I’m a feminist but they don’t call me an a**hole or jerk or douchebag, I’ve been called everything from whore to a cum encrusted guzzling slut. This makes me tend not to give MRA’s the benefit of the doubt about being misogynists. It’s probably not true of all of them but so far that’s been my experience.
Well now you have met an MRA that is not like those guys…LOL.
This is true.
