I cannot answer for all feminist, only myself. To me it’s about motive. I don’t mind anyone being helpful towards me and I try to be helpful towards others as well (especially loved ones). If a man helps me to my seat I wouldn’t be offended if he was doing it to show he cares. Others will have their own opinions on this subject though. :)

I like to read about “love languages”; which is the idea that we show our love/caring in different ways: verbal ( “I love you”, “I care about you” ) physical (touching, holding hands, performing tasks) etc, etc. I won’t fault someone who shows their caring by performing tasks like escorting me to my chair.
