I admire the original poster for having the guts to ask this question. Anyone who is willing to be vulnerable gets my respect.
I agree with the first portion of what the handsome gentleman from Kansas said but disagree with the final comment that if one says they would not date or foster a relationship with someone overweight it may show a sign of being shallow. I think thats jumping the gun a bit. Although I do get what you were saying.
I'm sure he would agree that being put on the spot to explain why a person may not wish to create a relationship with someone overweight would also be a vulnerable position to be in because they risk being labeled "shallow" when they are far from that. It would be no more shallow of an overweight person who also has certain tastes. Perhaps there is a certain ethnic background they are not attracted to. They themselves may not be attracted to overweight individuals.
In trying to explain peoples reasons for their tastes it all comes down to respect and the manner in which the person presents their reasons. For me personally, I can't rule out the option of dating a person who is out of shape because I've not been put in that position. However, there in may lie my answer. I've never sought that out. As simple as a matter of preferrence. I don't consider that shallow. We all have tastes that should be respected and not second guessed. I prefer someone who is taking care of their body. That would be my ideal choice. BUT my option remains open. I will never ever exclude someone out of my life based on physical appearance. I may not feel an initial physical attraction to the individual but I would be completely ignorant if I didn't allow myself the privilege of getting to know that person. Anything may come out of that situation
I can only speak for myself but thats about as real as I can explain it for me. Bold question. I'm impressed.
