Just grabbing this bit here Vik, because a really super easy way to prove this point is to demonstrate to the person that they already are an atheist. They already don't believe in every other god save for their own. Its their own specific religion that they are blinded to the faults of.
Uh... nuh. Not at all flying. If I'm a theist, I'm believing in a divine person, simply speaking. What you're talking about is another kategory than the existence of divine persons: It's the question of what form the divine person(s) take: Are they one or many or a few or...
So, you're makeing a category mistake in positing that the question which
form divinity takes has a bearing on the question whether divinity exists.
So when you say 'you should not have the freedom to offend someone' its actually a very dangerous thing to say, because again, offence is taken, not given.
Well, that is quite the simplification: You yourself explained how offence can be given, under the condition that the offender knows what offends. generally, there is a level of cultural and social knowledge that leads to some good idea what offends. So, given that, you have no right to offend (intentionally).
Also, not having a right to offend doesn't mean that it is necessarily prohibited to offend. Offence may be permissible in some cases, even if you don't have a right to it. If you do so unintentionally, you are not culpabale anyway.
All that said: I'm not against being offensive in some limited capacity: But when offense becomes so blatant that it devolves into hatespeech, then the victim has a right to protection - and the potentioal offender is oblieged to desist from those forms of offense.
Now, on to your proposition that you don't need evidence for beliefs to be reliable.
That's not my position at all. I said you don't need empirical (in the sense of scientific) evidence for
all kinds of beliefs to be accepted as reliable. For scientific theories, e.g., you do need empirical (intersubjectively checkable and checked: peer reviewed, observable) evidence to consider it reliable. In other academic fields, like the humanities observability does not take such a precedence, for example. mathematics, e.g., is largely non-empirical. Yet, mathmatical knowledge usually exeeeds the knowledge of empirical sciences by far in reliability!
I didn't say that Science is based in Faith, either. What I said is that if you want to justify science, you can't do so with science. You need a metaphysical fundament, that is non-scientific, to justify science as a process. One can do so, quite reasonably.
IF you stand by the position that all kinds of explanations and justifications need to be scientific,
THEN you have the problem where you are in a situation where the cat races after it's tail. You can't justify the principles you want to justify by themselves. The poition defeats itself, unless you commit to some fundamentalism, where science doesn't need justification, but is to be accepted without justification.
