The article asks: "Does this mean Texas must now offer a LGBT plate?"
Only if you want your tires shot out. But I'll give you 2 other examples where this may have a wide impact, if upheld.
When I lived in North Dakota I was considering a custom (vanity) plate for my motorcycle. Their state motor vehicle dept. has a website where you can create your proposed plate online. The program produces a very realistic, almost photographic image of what your plate would look like. Then you submit it, and if the plate's available, or not barred for offensive or sexually suggestive content, you proceed to the next step to buy it.
But a disclaimer does warn that all plate requests are reviewed at their main office, and the online program alone does not guarantee you can have it. So I tried several plates with GAY on them, and they all went through! But suspicious, I phoned their office, so as not to waste my time.
When I told them what I wanted, the lady instantly said: "Oh, no, we would never approve that."
"Why not? It's not obscene, and isn't barred by your list of proscribed plates."
"Yes, but people would object, and complain to us."
I didn't get my plate. Was my "freedom of speech" violated, according to the Federal Court ruling? Second example in my next post.
