I get the LGB and T but what’s the “I” for? In between?

I think the "B" for bisexual covers that one. Perhaps it means "Inquisitive"? I've never seen it before.

“Perhaps it means “Inquisitive”? I’ve never seen it before.”
You may be right. I’ve seen them use “Q” for “questioning”. But, any way that you cut it, the whole bloody thing’s absurd.
