maybe you should go back and read the other two definitions provided, the 1st and third that actually support my opinion. Let me save you the trouble and post them here so you dont get lost -
1.a: of, relating to, or characterized by sexual or romantic attraction to people of one's same sex
3.b: of, relating to, or intended for people who are gay, lesbian, bisexual, transgender, etc.
No need to argue anything, it has already proven my point in the very first definition. At this point, we can agree (based on Websters definitions) gay has dual meanings.
