Not wanting your kids watch 2 men kiss does not make you bigot unless you want them to watch a man and a woman kiss. A bigot does not necessarily mean eradicate. It also includes segregate which your post suggests as the solution making you a bigot.
See bigotry is simple, if an individual applies different standards for things based on race, religion or sexual orientation that makes a person a bigot. These standards could be as small as social acceptability. If you even think twice about 2 men holding hands while walking in the park but don't have similar thoughts about a man and a woman well then that's prejudice.
Frankly a little prejudice is normal even ok. There are a lot of different things in this world and its very possible that people are not exposed to many which in turn can make things seem abnormal to people. That's ok too. What's not ok, as long as the actions are legal, is when people try and prevent and or limit others because of these differences. That's bigotry.
