I get what you're saying. For a lot of people, they want to cut the meat from their diet, but they are either unaware of the other animal products, or don't have money to replace everything they own. Accessibility is a problem for some people. Personally, I hate how much we waste in the US. I'm not gonna buy new animal products, but I'm not going to throw my boots from 1996 away. "Needle and the damage done:" I can't bring that animal back, but I can stop contributing now. I don't see how throwing away the animal's sacrifice is helping cut down the industry. Not buying new products does more to stop it. In my humble opinion.
Many vegans would argue with me, but many vegans have a heck of lot more money than I do, too.
I think a lot of it is also ignorance (in the literal sense, I'm not condescending.) Who would think paper has gelatin in it? Who would think something from fish is used to clarify wines and beer? Who would think bone chard is used to make sugar whiter (not in all countries.) Who would think palm oil is causing mass deconstruction of forests and endangering species? Who would think diet pepsi has animal products in? WHY!? (ew, I don't drink diet sodas anyway XD)
My point is to say, animal products are used in EVERY aspect of products. On one hand, I respect that it's not going to waste: at least it's being used. On the other hand, it makes avoiding them all extremely difficult, and I dislike the loud minority of vegans who derive joy from putting other vegans down "oh, look, you're not vegan cause such and such." Dude, just pass the info on and let the person decide. They're like the "you don't really like anime, cause you don't like or know about or do this! I'm nerdier than you!" (ugh...I think I was that fan at one time o_O I'm so ashamed of myself!)
Again! I'm not shaming, just offering up some information, since I've gathered a bit over the years :3
