Now, where do you draw the line. What is the least sexist thing someone can do and still be sexist?
I really want to know. Opening the doors, paying for dinner, making the decisions of were to have dinner. I can go even further, making the decisions of the house, kids and family. What if the wife, encourages it?
I would not think it works like that. For example, consider my relationship with my girlfriend. I suspect that I will be in charge of technology issues and she will be in charge of child issues. (By which I mean, the person who has a little more responsiblity then the other, and which the other will probably defer to.) Is that sexist? Or is it because I am a computer programmer and someone who has spent his entire life wiring entertainment centres and building computer while she is a teacher and deals with children and children issues outside of the home professionally?
Sexist is when you assume something. I.e., that the man shouldn't make decisions about raising children because he's a man. Meanwhile many men are objectively better parents then the mother's of their children because they are more attentive to them and their needs.
If you have an equal relationship and decide on something then it is not sexist. If you assume that your girlfriend will do your laundry because she's a girl like your mom and your mom does your laundry now then that is sexist. However, if you ask her to do all your laundry and she accepts because she hates doing dishes and you do that, then there is nothing sexist about it.
Or even: If you decide to radically change your life to take a great opportunity to advance your career and make a lot of money, but as a result need your your spouse (male of female) to give up their job and take on all house and child care responsibilities, it's fine. Even if it's the woman who takes it on. As long as you come to it as two people in a relationship, rather than assumptions about who takes on what role. (I.e., the man is the bread winner, the mom should be the stay at home parent if and when the opportunity presents itself.)
As a man, I resent the stereotype that I should do all the heavy lifting and yard work. I detest those things. Being out doors. Breaking a sweat. Manual labour. There's a reason I gravitated toward computers. My significant other, on the other hand, enjoys the outdoors. In fact, I suspect she will do lawn maintenance, and she has hinted as much. We are moving in together in just over a month. We should clarify this. She hates dishes and I have no problem with them. I just put on a podcast or audiobook and go to town on them.
