Why be upset about the sky being blue?
Either way I think you're allowed to discourage whatever you want (assuming you do it in a civil way). Not everyone's going to agree though.
Some people are going to think/do things that you/I don't like. And sometimes there doesn't have to be some kind of resolution that comes out of it, some kind of trial and adjudication. Life can just go on regardless.
Yeah I think this is a good way to approach this. Absolutist views tend to be problematic. Society functions by breaking a lot of rules.
What if they helped you because you were funny, or kind, or intelligent, or any number of traits that are primarily related back to your genetics or upbringing?
This is how humans interact. It's rarely a concious consideration of the reason we help others, but it's almost always based on our perception of them.
This suggests otherwise. I personally would be very upset if someone helped me purely because they thought I was attractive.
