I think the difference is you can't change what/who you are drawn to. I've never thought, "Hey, I need to give short haired, chunky guys a chance otherwise I'm not being fair!" I'm drawn to lean guys with longish hair period. It's not really a conscience decision it just
is.
Like previously mentioned saying, "I will only date within my race regardless of whom I'm attracted to," is vastly different then, "I'm drawn to skinny, white boys with brown eyes."
You're trying to make an issue out of something that really isn't.
