Where this plays into people not wanting to be your friend because of different ideals is because THE OTHER PERSON IS AN IDIOT!
This doesn't sound too nice to iamzack now. 
But I think it cuts both ways. There are some things that should not offend you, and people's religions and ideologies are among those. On the other hand, there are some things that you should be careful about because they might offend other people, and that also includes their religions and ideologies.
Taking things out of context, if all you read out of my mega post was just the bolded idiot parts. Then you didn't get why the other person is an idiot in that scenario you quoted from me if it's not self conclusive enough.
People don't have similar ideals all the time, for the other person to think that they can't be your friend simply because of this is their own lack of intelligence that makes them think so.
There's people i disagree with all of the time, do i stop being their friend because they have different ideals than me. Definitely not, unless their ideal is pro-nambla.
Instead of dumb people stopping being friends with people of different ideals they don't agree with, how about staying friends and exploring why they feel that way.
Now as opposed to thinking of bluntness being part of iamzack's problem. I'm saying it's not. In my example of people not liking very many of the things come out my mouth with the girl who asked for advice about how to handle her drinking problem. It was simple enough, she got blown away by the fact of my extremely simple answer and was dissatisfied with it. A recovered alcoholic would have told the girl in my example the same thing, just probably not so in a nutshell with my delivery. She'd still have the same dissatisfaction towards the answer.
It's as simple as this Qent, people don't like to be sold on stuff they don't like to hear. To contrast this, there's enough bad deals going on in every single country where people get conned out of something for nothing because they kept being sold on stuff they liked to hear. Do dumb people who ask advice from a wise person go ape **** over the simple solution they got told? Yes, because they didn't ask a question being receptive to an answer, and secondly it was something they didn't want to hear (this second part really makes people unreceptive). Instead they want to hear of a solution they like, but hardly does this ever happen. And no, i'm not referring to myself as a wise man.
This is why i feel bluntness is not iamzacks problem with finding friends. She just needs to find real people to be friends with.
