Turned off by what? A tweet ... unless for couple of million participants in the oppression olympics, for the sane people having said or done something offensive is not a big deal.
If so many people were offended on the internet, is it that big of a stretch that people in real life might be turned off too? Just because you or I don't think it's a big deal does not mean that others might share the same opinion. I could easily see how someone might be turned off, especially before actually meeting the person.
