I've been online since... well... before the internet was a thing, really. Back when it was all bulletin boards and CompuServe and modem-to-modem and stuff like that. In oh so many ways, things have changed radically from those early days. But not everything. Some things haven't changed one damn bit.
Here is how online forums have worked since the dawn of time...
Poster: I am a bit confused about something and would appreciate people's experiences and opinions on this matter.
Me: Here is my opinion and my experience from having this opinion.
Commenter: YOU ARE WRONG! YOU HAVE BAD INFORMATION! GO FUCK YOURSELF!
For a goodly chunk of people, it's never about presenting their own opinions and experiences... it's all about attacking people who have opinions and experiences that differ from theirs.
Responding to some topics is more likely to invite an attack than others... like... say... "What's the best brand of mobile phone, iPhone or Android?"
Another example? As I found out last night, coming out against declawing cats is a topic that invites all kinds of attacks...
My opinion on declawing cats is pretty cut and dry... you just don't fucking do it. It's not like cutting your nails, it's like removing the entire tip of your finger down to the first knuckle. And if you're okay with doing that to a kitten, then you probably shouldn't have a cat. I would let my cats scratch the shit out of everything I own and still never consider maiming them like that.
I'd buy a shitload of scratching posts and cardboard scratchers, put them next to everyplace that my cats want to scratch so they have a more pleasing alternative, cover them with catnip to make them more attractive, put sheets of double-stick shelf-paper on things I want scratch-free to make them less attractive, then slowly remove half of the scratching alternatives once I figure out the ones they prefer.
Time consuming and expensive? Yes.
But it worked. My cats have their claws and me and my furniture are still in one piece.
Though some of my IKEA is sporting scratch marks from the training period. Oh well. Small price to pay.
Of course, there are people who have different opinions. And they are not afraid to attack you because of it. They call you names. They tell you that you're attributing human feelings to an animal. Provide "evidence" that declawing is not inhumane. Berate you for trying to make everybody hate them because they support declawing. Etc. Etc. Etc.
All I did was provide my opinion and relate my experience, as requested. I don't really give a shit if people want to attack me for it. That's the risk you take.
I'm used to it. I have a blog.
