THe fact is that the brits got told what religion to follow with their monarch and the majority followed with that, unlike the Irish. There was some resistence of the conversion to the protestant faith when king Henry the 8th was refused another marriage from the pope so decided that the whole country should turn protestant to suit him and his new bit of skirt. The English followed with power because that's what they do.
Well once again your trying to make it sound like a light bulb switch, one day were catholic next day were protestant tomorrow were buddhist. The whole conversion wasn't just over abit of pussy there was power and politics involved, i like this deep rooted catholic loathing going on here its very amusing. He basically made alot of effort to be a powerful infleunce in european affairs he helped back one side in a feud and when this side eventually won he was hoping this "favour" would get him elected the title of Holy roman emperor (your a catholic you should know what thats about) but instead the person he helped got the title and he was just given a lousy half arsed "Defender of the faith" title instead, still used to this day on coins and such, as a thankyou. Then theres the producing of an heir issue. See the pope exercised alot of power here say you married a wife who was infertile or had birth problems etc what happened then? An entire realm could plunge into chaos on the wim of a powerful man sitting in the vatican in rome.
Let me also point out another thing, every nation in europe which converted away from the catholic faith has done pretty well for itself
The UK
Netherlands
Germany
Sweden
Denmark
Finland (when they got away from being russian owned)
Norway (okish)
Catholic nations that are has beens or flopped down
Spain
Portugal
Italy (a shamble performance)
Greece
Hungary
Scotland (bankrupted itself)
