"why should Christians be mocked for thinking it was planned and Atheists like these guys think they are worthy of more respect for thinking it happened accidentally.It does not make sense to me."
I don't agree with Dawkins et al because they make unproven claims like the religious folk, but if I were to rank beliefs on a scale of respectability, Occam's Razor would mean I would rank theirs higher than yours.
"I actually object to being accused of indoctrination and that no-one can challenge my opinions."
I didn't accuse you. It wasn't your fault.
You are obviously wedded to your opinions and take any challenges to them as people being rude, evangelistic, etc.
"I am more than happy to be challenged as that is how we learn."
Re origins of the universe, how we learn is by reading about the staggering advances made in this domain in the past couple of decades, the experiments currently being undertaken, and the theories that they have launched and supported. Not by asking the same binary question over and over again and thinking it means something.
"Many of my Christian friends see no conflict with big bang/evolution and their faith."
That would be the clever ones who don't deny reality to fit their dogma. A deity can very well have created our universe with a 'big bang' and let evolution take its course to produce us humans. There is at least acceptance of proven reality there.
With flat-earthers and young-earthers, you just wonder what has gone wrong with them - hardware or software.
