I certainly do not mean to cause offense to LGBT people, in fact I am one of them!

I don't see how having a CLI tool that prints our flags insensitive tho.

not all gays subscribe to being flamboyant/colourful

There are some stereotypes that are considered funny by both; those the joke is about, and everyone else. A look at the crowd at any Pride parade suggests rainbow colours on everything is pretty much universally humourous.

Everyone hates hatred. But this particular stereotype has rather a positive, celebratory air to it.
