Probably but if it is as he states more then half the population I doubt that all of them are. I wouldn't be surprised if 20% or 25% of a population were some sort of LBGTA+ but half or more being solely lesbian or bi is to much.
According to the statistics in Iceland around 15% of the population is gay or bi (around 10% gay and 5% bi) and I think I've heard similar numbers from other countries so factor in other LGBTA+ and closeted people and yeah you might reach 20-25%.
But the CIS is in league with the emperor! Clearly they are evil!
