I'd love to see the research studies, statistics, or what-have-you to back this up. Something other than anecdotal evidence or personal bias, as neither of those are reliable sources of information.
Anyway, all a standardized dps parser would do is...nothing except make dps reads more accurate. They are used regardless of ToS, and people still get harassed and get kicked from parties for poor performances. If there were a standardized dps parser, and you're still getting harassed for your poor performance, you can still screenshot/report. Or you can improve your gameplay, but that may take a little work.
If used correctly, it's called accountability. If a player wants to participate in a raid, there is nothing wrong with expecting that person to improve if they are holding the group back, or get dismissed from the group. Heck, even if the group is doing ok, but that person has huge room for improvement, there is nothing wrong with expecting that person to improve. If people are wanting to raid, they should expect to be held accountable for their performances. It's just that with dps, there has to be a parser involved. Parsers just happen to also provide useful performance information for tanks and healers as well.
