Personally I put it like this.
A good friend of mine, a very staunched atheist who doesn't mind speaking his mind, was watching television one day when I stopped by to drop some things off which he had asked for.
As I walked down the footpath which led to his front door, I could hear the cursing coming from his lounge room. He was watching some evangelist on the TV.
"What the hell, are you watching that for, if it gets you so uptight?" I asked, him.
"They shouldn't be allowed to have that sort of rot on there," he said, to me in reply.
"Some people do not consider it rot," I said, in reply, "Besides, if you don't like it, change the channel, switch it off, or do something different till it is over."
On a personal level, I do not know which is worse, evangelism or watching some person prance around their lounge room like a raving lunatic on some personal evangelistic crusade of their own. As he was a real person, I couldn't change the channel, but I could certainly drop the things off and leave. Which is exactly what I did do, telling him I would give him a call when he came back to reality and was a sane person once more. He is an intelligent man, he got the message loud and clear and apologised later.
There is an old saying, be careful of what you wish for, for it may come true.
On a more personal level, I would rather a world full of evangelists who just sit quietly and listen to some other person talk, sing a few songs and be happy together, than a world full of raving lunatics who fly off the deep end with everything they personally don't like.
