Who you calling a proselyte?

Word: Proselytize
Source: "The Slow Life Picks Up Speed"- article from the new york times.
How it is used: "But it does have an increasing number of proselytizers, like John Brown, an architect in Calgary, Alberta, whose year-old Web site, theslowhome.com, urges consumers to say no to “fast-food architecture,” and Geir Berthelsen, a Norwegian motivational speaker whose Web site slowplanet.com, which is to go online in mid-March, has as its goal to be a hub for all things slow, from slow travel to slow shopping to slow design, he said. Ms. Chanin, meanwhile, has a book, “Alabama Stitch Book: Projects and Stories Celebrating Hand-Sewing, Quilting, and Embroidery for Contemporary Sustainable Design” (Stewart, Tabori & Chang) due out in March."

My sentence: My friend Chris is in a frat. he is always proselytizing trying to get me to join the frat. also. It gets old real quick.

You know it is funny, when I found my word of choice I also found a typo. The wrighter of the article uses the word "proselytizers" which is not a proper ending to the word proselytise.
