Nick Apex, LGBTQ people do need allies. The examples and reasons to prove that are too numerous to mention. Allies are the people who stand up for and help lend support to people who do not have the same rights and privileges as others.
Using your logic, what would happen if leaving your house was a threat to your life? What if, for whatever reason, the colour of your hair, which was impossible to change, were the reason for your otherness and inequality in the country in which you lived?
Could you live your live as an individual? Of course you could? But how fulfilling would your life be if you were refused service at a restaurant because of the colour of your hair?
We all desire the same thing: to live our lives, BUT with the QUALIFIERS (meaning with quality) of freedom, acceptance, equal rights, etc.
This, in part, is why we appreciate allies, because those individuals see the injustice of rights for some but not all.
Your “opinon” does not support equal rights.
