Here's something to ponder.
Why does Wikipedia have a specific "LGBT" tag? Of course, that's "lesbian, gay, bisexual, transgender". This is the name of a modern political group/movement - some loose alliance of a diverse collection of people. It's weird and inappropriate to apply this tag to freaking Sappho of Greece, as if she were a proud member of what's largely a 20th century socio-political grouping.
Gay men and lesbian women are not identical. Even where their inclinations are concerned, there are different motivating factors, and likely different physiology in play. Bisexuals? Don't get me started - they're the red-headed stepchild of the entire movement, at least next to the "transgendered". And "transgendered", while it has its own problems, is utterly unlike homosexuality or bisexuality as offered - it's a state of physical impairment requiring corrective surgery, and that's only if you don't consider it to be more properly considered a mental impairment.
This tag should not be in use on the wikipedia. But I will say this - once again, you can admire the group for the sheer ferocity they have. These guys will plant a flag anywhere they can. Learn from their group, even while you try to reason with them individually.
