Coz it's fashionable to like fags.
People like jumping on bandwagons and making villain figures out of the ones that oppose their beliefs. When it comes to hot topic stuff like sexuality, race and religion there'll always be people who side with the defending party even if they don't fully support the idea.
This can be frustrating, but also means they can often be easily manipulated for your entertainment. Besides it's the internet, who honestly gives a fuck what people really think?
