It's hard to have an honest conversation about gay issues because liberals treat anything other than outright celebration of all things gay as "hate." That doesn't leave people much room to discuss a complicated issue that involves real human beings who often have to deal with a lot of challenges because of their sexual orientation. If you're a compassionate person, you have to feel some sympathy when you talk to people who are closeted because they're afraid that their relatives won't accept them or someone who feels isolated and alone because his sexual orientation makes it impossible for him to have a romantic relationship with 98% of the population. Life is hard for most of us -- and if you know people who are gay, chances are you recognize that it's even harder for them.
Yet and still, you can't deny reality because there may be a few people who don't want to hear it. Sure, you don't want to unnecessarily create pain in people's lives, but ultimately, nothing creates more misery than abandoning common sense because the obvious truth might hurt someone's feelings.
1) You can't change your gender: Have you ever heard of Body Integrity Identity Disorder? Long story short, there are people out there who believe they're "supposed to" have less limbs. Maybe they want to get rid of an arm or a leg. The "problem" these people run into is that surgeons consider it unethical to remove a healthy, functioning body part and refuse to saw off their limbs. Instead, they just refer these people to a psychologist. That seems to make sense, doesn't it?
Yet, when we have people who want to mutilate themselves to "change their sex," we don't treat that as a mental disorder. Instead, we take it seriously. So seriously in fact, we have 9 year olds getting hormone treatments so they can pretend to be another gender.
