Well, according to lore, female Gorn look similar to males, but on average larger, and do not have "spikes" on their heads, which is a trait some but not all males do have. This description matches rather well with some of the "Qo'nos civilian" NPCs walking around first city. So while there are no female Gorn in the KDF, it may not be true that there are none in-game.
If you want a female Leezard, you can make a Female Saurian for the Fed Side.
Constant exposure to the same opinions leads to continual reinforcement of ideas until eventually, any challenge, no matter what form it takes, is going to be met with a disproportionate sense of outrage. Room for reasoned discussion can no longer occur.
