No, if you become a vegetarian or a vegan, no one is going to force you to eat tofu. But if prepared well, it's something you might like. Check out some of the cookbooks and recipe sites I recommend for more on tofu preparation.
I am a vegetarian. That means I don't eat any kind of meat. That includes fish, chicken, turkey, cow, sheep, calf, clams, or anything that could be considered flesh.
Those of you who have been to this page before may remember that I was vegan for quite a long time. I can't say that I am anymore, I do eat foods with some dairy and egg products in them. But I don't rely on these foods by any means. We still use soymilk instead of dairy milk.
I could go into the health, economic, compassionate reasons to go vegetarian but many others have explained it much better than I could. Read something from the recommended reading list, or check out a link.
RECOMMENDED READING: For ethical and environmental reasons to go veg, read "Diet For a New America" and "May All Be Fed, Diet For A New World" by John Robbins.
For health reasons to go veg, read "Food For Life" by Neal Barnard, M.D. or anything by John McDougall, M.D.
Cookbooks I've been using lately are "Simply Vegan" by Debra Wasserman, "The Meatless Gourmet" and "The Meatless Gourmet, Easy, Lowfat and Fast" by Bobbie Hinman, and 1001 Low Fat Favorites, by Sue Spitler.
