There is a lot of misunderstanding about the call letters. WLGBT isn't a very popular station.
First, it is a political caucus. That's it. It's not a subdivision, not a community, and not a subpopulation with a monolithic set of values or perspectives. What we have in common is a political goal to see full equality in the law for our constituencies.
A good parallel would be the U.S. Democratic Party. It's an alliance. The big tent encompasses feminists, racial minorities, labor unions, ecologists, gays, and others. That doesn't mean a wealthy white gay member and a black preacher from Atlanta have too much in common in their views about religion or gay rights. It just means they have more in common as a caucus than they do with other parties that have any chance of getting elected in Atlanta.
And, a wise caucus speaks on the platform issues they can speak strongly on, and saves the disagreements for non-party venues, else the caucus presents as weak.
LGBT has long been a caucus with deep divisions. Many, many lesbians and gays do not even endorse transgender surgery, although we defend the right for an individual to make that decision and to be protected in society and in law. And we have seen on this board more than a few attacks on bisexuality, condemning it as little more than closeted homosexuality, so let's not get all panty-bunched about the demand to respect everyone equally. That goes double for the vaginaphobic comments that are perennially posted.
I've lived in four corners of this nation. I've not seen any tight social community of gays and lesbians and transgendered and bisexual people. I have seen social groups where they gathered politely, but even in those selective gatherings there were obvious fractures and divisions and even antipathies. They did serve to represent, in a loose way, the larger LGBT populations.
But, be very clear. No one speaks with any authority in defining what is or isn't an LGBT value, political view, standard, etc. Representatives are nominal, and are not elected by any national poll. That means, by definition, the representation tends to be outspoken and to overreach often in the effort to shape what LGBT should be.
On this forum, many is the time when a few have posted propaganda to disown public gay figures who have not been poster children for some member's litmus tests. It mattered not a whit. Sexuality is sexuality, not an oath of political allegiance.
The call letters can be as long as a DNA strand for all I care. I don't use them, and refer to gay and gays. When I'm voting, I'll be falling into a caucus that inherently includes them all, as even combined, we constitute a very weak minority indeed, both numerically and politically.
We would do well to remember that we advanced in gay marriage not by political success as evidenced in legislatures, but by judicial actions. Just as the women's suffrage movement languished a century in the struggle, we have yet more decades to become fully equals in society.
