Hmmmm.... nothing in there about power.
sex·ism /ˈsekˌsizəm/
Noun:
1) Prejudice, stereotyping, or discrimination, typically against women, on the basis of sex.
Sure... it says typically against women. But if sexism against men can not exist then that definition would have to say always... not typically. So you might not want to accept it... but your statements are wrong... plain and simple... wrong. You can't just make your own definitions for words and then project them onto everyone.
Quotas discriminate. Period. If the rule says you must have 50% women and 50% men, when it comes time to hire a new person, you absolutely will have to take the gender of that person into account in order to make sure you stay within the quota. I have absolutely no idea how reasonable people can think quotas are anything but discrimination.
I'm not part of the MRA. But go ahead and lump me into the MRA group if that is what you need to do so you can laugh at me. I really don't care. Because that would just be one more thing you are doing to water down the real issues. You do your cause no good to be like that. Overuse of words that used to mean something is becoming the butt of jokes! You are making them a joke. Go laugh at that. Wolf! Wolf! Wolf! Eventually no one will listen anymore.
