Charles Carey, the others only have a point if they've got the proportionality calculated correctly.
You, yourself, said: -
//Yes but that is precisely the point ('People of all faiths') but that is not what is happening, because it is mainly the Christian faith that takes the flack. //
I am able to read that sentence and take it to be a sign that the Christian faith is still in the (numerical) ascendency, in this country. More of them, ergo, more examples, anecdotal or better, there are of incidences of them taking flak.
(And it is spelled flak, btw. It's a loanword). ;-b
All the same, on a point of pedantry, I'd like to know whether "persecution" is too strong a word? It's one thing for people to give you grief, verbal, hassle etc. but it's something else to have your church or home firebombed, or for your entire community to be rounded up and gunned down, like in Sudan, Syria or wherever.
