Lets not go down the path of even suggesting that Ukraine is not worthy of our support if they do not have the same level of LGBT rights as North America or some parts of to use a Rumsfeldian phrase, some parts of "Old Europe" have.
Personally I hope LGBT rights will improve in Ukraine because I believe what consenting adults do is their own bushiness.
But if a country like Italy still has a long way to go which I'm sure most people here know was a founding member of the EU and NATO, lets not get hung up on this issue while Ukraine is literally fighting a war for its survival.
On a side note I had no idea Montenegro was so LGBT friendly until I looked at this map.
