My actual thoughts on the issues related to inclusion and deletion are not what I was trying to address. I contributed to Wikipedia for a time and saw and was part of deletion sprees on both of the sides. Something like this happens every three months I would guess. Mostly, my thoughts on it at the moment are 'not this shit /again/'.

If something keeps cropping up again and again, that says to me that there is an expectation that is not being met.

Either wikipedians can try to change the expectations of the entirety of the rest of the internet, or they should deal with their internal problem.

As far as i have ever been able to determine, the only people who support deletionism are a subset of wikipedians.
