I don't see why you need to rate them. What problem does this solve?

Posted talks on the internet? Well, you're on the internet, there's 5 million things worse than what you're watching, all fewer than 3 clicks away.

At a conference? If you're going to a professional conference then you're probably old enough to be aware that such things in the world exist.

Would someone skip an event because they might be offended? My opinion would be to let them be offended. If many people are offended, the speaker isn't appropriately addressing the audience (in which case they won't be a speaker next year), and you always have the option to just leave the room.

I've been in talks where 20% f the audience got up and walked out and that person still has a strong speaking carear. To many customers for events vs good events.
