First, you cannot make conditions like that, I might disagree with you but simply not see your post.
Second, congratulations on completely misunderstanding my posts. I am consistently of the view that there is nothing sacred about flags or symbols. But elsewhere I clarify that I don’t deny their power.
Burning any flag doesn’t imply blasphemy or desecration. The US flag is the symbol of the most powerful, most militarised country in the world. It’s a political symbol.
An LGBT flag, assuming there to be such a thing, is a symbol of a minority which until recently was powerless. That minority deserves protection, and I consider that any physical or expressive attack on such a minority is a bad thing. I disagree with the current interpretation of the US 1st amendment on hate speech and agree with the European position. (Westboro can’t come to the UK, and if they did they would get arrested.)
Burning flags, which are abstract symbols, is OK, except for any civil damages if someone else’s property is involved. Burning people isn’t.
[edit - I would add something else. LGBT people may not identify with a flag; I am especially suspicious of people who claim to speak for other people, or who tell people to “unite under” some symbol.
One of the first such symbols, the Roman Fasces, was a bundle of sticks and an axe. Its literal meaning was “do as we say or we will beat and perhaps kill you.” Some flags since have really meant little else, like that of ISIS/Daesh, or Confederate flags being flown to warn black people to stay out of an area. The same symbol can have different meanings at different times, another reason symbols should not have special protection.]
