Maybe one should read the Declaration of Independence then. Especially the part "where all men are created equal."
And all men can equally decide whether they want to get it on with some other man's but, and can thus be equally held accountable for their decision!
Anti-discrimination laws telling business whom they must hire, and telling landowners whom they must rent to are a huge curtailment of private property rights. One can argue about whether this curtailment is justified in the case of race. But sexual perversion? Come on.
All men are "created equal" in the eyes of the law. But to say that all private citiziens must treat everyone exactly the same, regardless of how they behave, is to completely take away our rights to property and freedom of association. That's not what the Declaration of Independence means, either.
