Just out of interest, why did the rainbow become their target, then? I thought it was because they were anti gay rights
The rainbow, as has been repeated many times by authorities such as the city council and priests, stands for nothing in particular. One priest even reminded people that rainbows should remind us of Noah.
Ah, so just decoration? Seems odd that it drew their fire! These things are seldom just decorative though, surely. These rainbows must have some symbolic meaning, for now I will assume it's something like equality, although I was told they were a gay symbol and that's what irked some knuckle draggers.
