I guess I'm an exception to this rule - but only selectively. I am typically a gentleman...I hold doors for ladies, open car doors, allow them to proceed first thru stop signs, etc, etc, etc. But this is in the real world. It is in my opinion that by making the conscious decision to go to WDW, you are implying that you understand that everything is first come - first served. This goes for lines, buses, food, etc. If i were to stand at the entrance to a ride queue and let every lady go first, I'd never get thru the park. Sure, I'll still hold a door for a lady if I'm in that situation, but if I get to the bus stop first after treking thru the park for 14 hours, and get a seat on the bus, I'm pretty much going to plant myself unless it is a severe situation.
If someone is SO pregnant that they need to sit everywhere they are, it just seems silly to me that they'd put themselves through that misery anyway - but I don't think I'm obligated to give up my seat to every person that thinks they need the seat more than I do. That's selfish, in my opinion - you can say that's hypocritical of me, but if my feet are aching so bad I have to keep shifting my weight, and I'm chaffing, and I'm sunburnt and exhausted, I feel that I have equal right to sit down on the bus than ANY other person there. If I'm THAT bad, and I see that I'll be standing on the bus, I'll sit on the bench at the stop and wait for the next one and be in the front of the line (without cutting). I feel that I'm being less selfish there, by allowing at least one more person to ride that bus, who may be in more of a hurry than I - and one more person gets to sit on the bus.
I know I'm going to get yelled and at called sexist or inconsiderate, but I'm FAR from either of those. I just consider myself equal to everyone at WDW, because we all made the decision to go, knowing full well what the conditions are before arriving. Now, like I said, there are exceptions - when guilt or compassion takes over, and I give in - so I'm not 100% coldhearted
