Opinions are a statement of personal preference. Of course I disagree with you but I can prove no more than you can that either is right or wrong.
The difference, however, is that what you believe is right affects the freedom of homoloveuals, and what we think is right is trying to stop that. Sure your opinion can be whatever you want it to be, but that opinion shouldn't affect the lives of others the way it does now. Such as open hate and lack of freedom.
Not necessarily saying you do that, but in general, intolerance leads to this. I'd like to ask, when has intolerance ever been the right thing in this world?
