It might be worth considering that if all you ever do is verbally abuse them, they might not be very receptive to what you're saying.  It's not just about having a good idea, it's about how you present it and (particularly in your case) how you conduct yourself while doing so.  

I could have the best idea in the world, but if I spent the entire time slagging off the people who I'm trying to convince to adopt it, it stands to reason that's not going to go the way I'd like it to.

It's overly simplistic to talk about whether developers "should" or "shouldn't" listen to the community.  It's not that black and white.  Each and every single idea has to be treated on a case-by-case basis.  What this is really about is that each developer and dev team is naturally going to produce the code which they believe is most likely to lead to Bitcoin's overall long-term success.  It's not practical for them to implement every random idea people throw out there.  Many of the ideas people suggest (or demand) are not viable.  So they have to be selective and focus on the few decent ideas.  But how can they know your idea is decent if they can't even hear it over all the conspiracy theory babble and outright FUD you constantly spout?  If you want the community to take your idea on board, the onus is on you to present a reasonable argument to support your case and convince them that your idea is actually worth implementing.  Then, with community support, developers are more likely to listen.  If they are then convinced your idea has merit, they are more likely to implement it.  Or, as always, feel free to skip that process and either pay someone to code it, or code it yourself and see how the community reacts then.

But don't just demand shit like an entitled child and then insult the developers when they inevitably ignore you.  When has that attitude ever worked for you in the real world?  That's not how you get what you want.  Try being an adult about this.  Yes, I think you have a good idea, but you really need to work on your people skills.  All you've earned for your efforts so far is negative feedback from a developer.  If you had been more reasonable from the offset, things could have been very different.  Seriously re-think your posting habits and mannerisms in general.  You only have yourself to blame if people aren't taking you seriously.

All that put aside, I will start a topic about fee priority for you if you don't think you can conduct yourself appropriately.  But I think it would be healthy for you to start one, while taking on board what I've said above and really watching your tone.  Maybe even open with an apology for your behaviour to date.  It's not too late to change.
