Those arguments are just about creating larger conversations through the smash and grab of polemics
This is fair to a certain extent: I get what you mean, but I do think it is the philosopher’s duty to try to rise the conversation to a level of ample clarity.
I've been an atheist since the 1970's. In relation to the New Atheists - I haven't read their works.
To be fair, ‘New Atheism’ doesn’t forward particularly new ideas; but it has made quite a bit of them notorious around these parts. A lot of what you have been saying is straight out their old text book, although I understand you are not intending it that way.
For me atheism isn't a positive claim that god doesn't exist. It is simply that I am not convinced
I would say this is agnosticism (viz., the suspension of judgment about a proposition); whereas atheism, traditionally, is the belief there are no gods.
To me belief in God is similar to a sexual attraction - you can't help who you are drawn to
I would say, even if this is true to some extent, it is irrelevant to theology. Either one has good reasons to believe God exists or not.
The arguments in my experince generally come post hoc.
That is fair: most people do operate this way, and Nietzsche calls it the Ass arriving most beautiful and brave.
I would say that I have a reasonable confidence in Bob's judgments because he has empirically demonstrated himself as reliable over many years
Having this reasonable confidence in Bob is trust—no? You trust him. Right?
However if Bob said to me, 'wash your hands in this water and you will be cured of any cancer because the water has been impregnated with a new anti-cancer vaccine', I would not accept his word because the claim requires much more than trust. It is an extraordinary claim
There’s a lot to unpack here; but the most important note I would make is that you are suggesting that some claims cannot be validly believed through trust in an authority; and to me anything in principle is on the table. If there are sufficient reasons to trust the authority, then one should believe it; and if there isn’t, then one shouldn’t. However, to say that some claims are “extraordinary” (which is straight out of Hitchens’ playbook btw) that cannot be, even in principle, verified other than through a belief devoid of trust—well, I don’t know what that kind of claim would look like.
The reason you might not put your hands in the water (given your version of the thought experiment) is that you don’t believe Bob is qualified properly for you to trust him in this regard. Imagine, e.g., Bob was an expert—certified—doctor that pioneered this new anti-cancer vaccine and was ultra-truthful (like before in my version of the hypothetical): would you trust him then?
when I am talking with someone who says they have it on faith that homosexuals are corrupt, I can safely tell them that they are using faith as a justification for bigotry and for a lack of evidence.
This doesn’t make any sense on multiple different levels.
Firstly, if they have it on valid faith, in principle, then it would be warranted to believe it; and you are implying it would be irrational for them to.
Secondly, homosexuality, traditionally, being immoral has nothing to do with corruption per se: it has to do with a person practicing in alignment with a sexual orientation that is bad; and it is bad because it goes against the nature qua essence of a human.
Thirdly, saying it is bigotry and that there is a lack of evidence to support homosexuality as being immoral just begs the question. For me, for example, I do think there is good evidence to support homosexuality as a sexual orientation as being bad and practicing it as, subsequently, immoral.
