 ::::Strictly speaking, there is a way. You give up (nearly) everything else you do, and spend all your time on Wikipedia, persuading and encouraging the sort of culture change needed (which includes ensuring the same values are passed on to the next generation of Wikipedians). If your argument is reasonable, you stand a good chance of achieving some sort of change. But most people are sensible enough not to do that. A couple of hours a week, or in spare time, isn't really enough any more. And that is not good. I think UninvitedCompany pointed this out a long time ago now, but it's always been a problem - how to get enough traction both in the face of general apathy, and when there is opposition from those with (for whatever reason) more time to spend on Wikipedia, and the willingness to dominate discussions. This reminds me of who the top contributor to WT:RFA is, as one of the arbitrators pointed out recently.
