I guess that depends on how insulted you feel about stuff you don't believe in by people that don't care about you. Sticks and stones IMO.
Insulted? Most people have no idea what real insults are. Those that can't swim in the deep end shouldn't jump in the pool.
But I don't think that person is indicative of all believers.
All believer, by definition, believe in things with out evidence, leading us to...
And even though they believe in something I don't, as long as no harm is done and we all go about our lives, who cares?
Religion often has harm on in it's name, particularly when religious beliefs are allowed to penetrate secular law and society. We are all better off for having our beliefs challenged and not being allowed with getting away with saying terrible things in the name of love. This planet is ours and our children's garden, if you don't tend it, you've no right to complain about the weeds.
For you. For others, perhaps it's different.
Only until they try that on me. Then it's absolutely no different.
