Well, firstly I suggest you drop the attitude, it really adds no value to your posts. Secondly, avoid the big chunks of text, use some images (just not overused fail pics) to split it up. If you do need big chunks of text, use some formatting to make it prettier; centering, headings, etc. Rambling on about how someone sucks is boring to read, add a joke or two in, it doesn't have to be good but light hearted, to lift the negative tone. You don't want your tone to be negative as people will react to it, and will react to the thread negatively in return.
Ultimately, try to sound less whiny and make it more of a PnP statement. You want to show the world their failure and get people to feel drawn towards your side of the argument. The best ways are: humour, creativity, and intelligence. The worst ways are: Ego, dullness and stupidity(not saying you are stupid, but in general).
Just a couple of tips for when you make a thread.
