“but police prevent angry clashes between the two”
How in hell would thousands of bikers “have a clash” with 2 dozen losers?
LOL, I know!!
Actually, I believe there was a small "Christian" group (not related to the bikers) marching right next to the handful of Muslims who were marching... supposedly the Christians were constantly heckling the Muslims. I believe the police were trying to keep those two small groups apart.
