Creationism and ID is very hard to argue with people as they dont have any arguments in favour of what they believe. All the debate ends up as is science defending its position because there are no facts to attack in creationism.
And science has the paradoxical disadvantage that every year tens of thousands of papers are published for creationists to trawl through meaning if they bring up an obscure point it is very unlikely that the particular scientist they are debating will have read the paper so the creationist can claim victory and make the scientist look foolish.
The fact that a 10 minute reading of the paper would have shown the creationist view to be false is irrelevant in the heat of debate.
religion is the most hardest because people have their minds made up already when some one with a religion makes a mistake and then blame the whole religion for it.
Religion
Because when the world changes, politic adapt to it right away
But even this world collapse, religions would stand still thanks to hardcore believers
Politics. Whenever people are faced with the truth about religion they walk away. Once someone walks away likes that, they've taken something with them. Insight, logic, and truth - whether they admit it or not.
