Question yo. For people who have been doing this a long time

Let it roll over your back.

Become an observer. Absolve yourself from having a stake in things. Observe the homophobia like a detective - where it is said, by whom, and why. Don't judge. Assess why the homophobe says what they do.

Are they covering up for their own sexual insecurities? Are they ranting on their radio show to boost their ratings? Are they claiming homosexuality is a "sin" as a platform for their political career?

Start seeing it this way and I guarantee you'll gain a healthy amount of confidence about it. When you're angered by it, You give it power.

You make things change by being sure of yourself. Be firm in your position - but always be open to new points of view. You were born this way. Any problems someone has with you is just that - THEIR PROBLEM.

 

^^^I like this answer. You should always assume that someone who's saying homophobic things is either confused/making a cry for help, and if they are you should kindly and calmly help them. If they're just ignorant and hateful, chances are arguing with them will just add fuel to the fire.

Courtesy is your best weapon.
