One Thousand Words

If a woman is bigger and stronger then you just have to avoid getting into a fight with her. Life's tough like that. There is nothing stoping a pregnant woman standing up on the train either, they should be exercising right up until childbirth anyway, but it is just societies rules that make you give up your seat. It isn't fair but then again you're kidding yourself if you don't think women have it far harder than men in the discrimination stakes.

Is that unusual ?
I'd probably act in the same way as you in that situation.
