Yes. Absolutely. Sometimes it is nice - doors opened for me or help lifting heavy things. Sometimes it is not nice - my opinion dismissed more readily or being viewed as overly opinionated if I assert myself. And lots more - too much to go into here. More as I get older as well.
I think the key to feminism is that it is about equal opportunity for both sexes. I consider myself a feminist because I believe that both or all genders should experience equal opportunity and be judged on their merits as individuals. It sounds simple but is difficult to achieve. I am a product of my generation as well and I know there are times when I unwittingly judge myself or others through my own sexist behaviour.
I appreciate the opportunity to have this exchange with you! It is conversations like this that will hopefully lead to equal opportunities for all humans. Thanks!
