I'm not saying that at all. I'm saying there's a huge natural bias towards certain kinds of people and although falling in love itself certainly can't be influenced, there will always be loads of people that wouldn't fit my taste.
I'm simply convinced I wouldn't fall in love with such people.
When it comes to hating people that's a whole different story. I can't hate people that I do not know, hence why I said that it's certainly possible for me to become very good friends with someone in a wheelchair or even with the Down syndrome. In that case I really don't care, but falling in love is friendship on a whole different level. Of course there will be a huge bias towards certain people, that's just natural.
It has nothing to do with ethics, discrimination and all that. It just has to do with natural preferences.
( Not falling in love with someone isn't mutually exclusive with hating them either by the way. )
