Phil, I'll buy into your Third World Muslim terrorists case when you start counting in how many Muslims Hindus kill in India; how many Uighurs the Chinese Communists kill; how many Rohinga the Myanmar dictators kill; and how many Muslims in Nigeria Christian militias kill - because my understanding is that Nigeria and West Africa is a series of wars between ethno-religious groups with political overtones. My impression is that many more Muslims are killed than vice versa.Thats not true at all, there are lots of violent white supremacists. I'll never defend those idiots.
You however cannot admit (nor accept) that radical Islam is BY FAR the greater worldwide terror threat.
Point is that it's apples and oranges. If I start chucking in Third World conflagrations and then weigh them against small terror cells in the West, I'll get a massive imbalance.
So let's stick to ISIS, AQ and random Muslim wackos in the West vs White supremacist terrorist of either the fat, assault rifle toting middle aged variety or the skinny basement dwelling incel variety, also in the west.
I'll give the Muslims a head start with 9/11, but have the White Supremacists catching up little by little as Muslim extremism seems to be on the wane.
