What I'm trying to say is, you can have a movement that advocates for something without being ideological/dogmatic. A big problem with the MRM and, even more so, with feminism is that they cling to ideology, even when they are proven wrong.
I can't say much about the MRM off the top of my head. An example in feminism is the gender pay gap. Itdoesnotreallyseem toexist. At least not in the way most feminists think it does. Yet people still go around claiming that women earn 77 cents to a man's dollar.
I've heard a lot of different views on the wage gap some with more merit than others, but really there's no way to get rid of misinformation in any subject. For example science, or politics. The thing about feminism is there really is no governing body saying what's accepted as there is in some sciences. There's no "Bible" either as there would be in religions. It's really not regulated at all which I think was a good idea in thoery but really doesn't work in practical terms. It's a giant clusterfuck actually which is why I don't really get the comparison to ideologies or religion.
There really isnt even one bible. There are multiple translations and an infinite number of number of interpretation. Feminism at its core is about equality for women the same way that Christianity is about the bible. After that it's up to the individuals interpretation, does it mean mandated equal wages? Does it mean special rights for women that are in place to fight years of inequality? Does it mean that men should shut up and get back to the kitchen and have no property rights for the next 2000 years to counteract all the previous oppression . All of those could theoretically mean equally just like all sorts of shit can be interpreted from the bible.
