Well, because if you dish it out, you need to be able to take it. I've been inhabiting the flamiest of on-line forums for well over a decade, back before the web even, and I have a lot of practice with both. Of course, if you troll, you're diminishing the forum for people who are here for serious discussion, and some of those people happen to be on your side.
The frustration you express - that you can't find anything that refutes evolution - is inevitable when you challenge a well-established scientific theory. No established theory is going to be thrown out for a few anomalous results, because we know from experience that 99% of apparently anomalous results are not really anomalous, once you've investigate them. If and when evolution is overthrown - and I'd bet the farm against a cup of coffee it won't ever be - it will be a result of an accumulation of a large amount of contrary evidence, comparable in weight to the literally millions of pieces of data supporting evolution. There are no short cuts.

I have ONE thing that totally refutes evolution.
It's called the "born again experience"
You should try it you would like it forever and ever.
