I know you're replying to Burger, but I had some things I wanted to share about my views on this topic and why I personally think the way I do.
First, before I add anything, I must clarify I do not support/endorse/encourage any activity involving sexualizing a real life minor.
Now for my opinions on MAPs.
You mention that you view MAPs as a way to publicly signal a sort of "Hey contact me for you know what. ;3" And I'm not saying there aren't people like that, I'm positive there are. How I view it though is being a pedophile is literally the worst thing in the world anyone could be. Like actually a terrible curse. While i'm sure some pedophiles have no issues with this affliction they are given. I feel like the most unfortunate thing is that those who do feel bad about it have 2 options.
- keep it secret and never tell anyone ever and just try their best with their own thoughts.
- occupy other pedophile spaces and have other pedophiles tell them "you're normal, it's OKAY to sexualize children!" and essentially be sent to an echo chamber.
If a pedophile was to try and get therapy, they're going to get arrested, they're not going to get help (with a few exceptions depending on the country.)
I always felt that was the difference between "pro-contact" and "no-contact" MAPs, the "pro-contact" maps being more likely to be ones who are fine with their affliction and find absolutely asinine ways to justify it and indulge in it. Where as the "no-contact" MAPs are more likely to be people who admit "I have a problem." And I know this isn't the case for everyone. I just think excluding these people just serves to further radicalize them.
This is basically my opinion on other groups as well. I believe that blocking these people off just serves to further radicalize them as they find their own little echo-chambers which do nothing but encourage ever-growing dangerous urges and behavior. This isn't saying that this will prevent people from finding those places and going into those echo-chambers, but it's giving them the option not to.
To be clear I'm not asking you to change your opinion. You seem to be rather reasonable as to why you think what you do, I actually appreciated the clarification in your post. Wanted to kind of do a little clarifying of my own.
