It's hard to Unite when you're perpetually under siege, being taken as slaves, looted, raped. They just got outplayed by the Bolshevik tactic of infiltration, not invasion - makes being a good warrior not mean much on the physical side of things. Yeah Bulgarians are a rare breed.
At least the Ottomans gave them opportunity to be Janissaries and hold high positions in their Empire and raised them to be Soldiers of God with an excellent education and opportunity to marry after the age of 40.
You might be naive thinking Gypsies are harmless but behind the scenes they are very tribal and do sketchy things all throughout Europe in general. Ottomans only recruited 3-5 thousand children from the Balkans every 2-3 years, at least for a purpose beyond prostitution.
Darren Beatoff compared Janissarries to Trannies (Tranissaries) which isn't even a good comparison and honestly an insult. Janissaries defeated the monstrous Roman Catholics which held Europe in the Dark Ages for 500+ years and worked for God. Notice how Europe still had their history, culture, and monuments / artifacts intact after Ottoman occupation?
Long story short, rape and murder are the staples of human history, so the only metric you can go by is who did it the least and with as much positive intention as possible.
