It isn’t discriminating.
Just like the Catholic religion, where women and men are “different” but one is not considered or represented as “better” than the other…and men are priests and women are nuns but neither is considered superior, just unique for each gender…the term LGBT merely lists the “different” categories…and, like the church, is not discriminating against either one of them even though one letter is before another in the initial line-up.
One more example: If a woman gets married and adds her name to her husband’s, but puts his first, it does not mean his name is superior, right? So, the order of the words/letters do not matter.
But you all know this.
Why make fun of these people who are different than you? Even joking that animals should be on the list?
It is not kind.
