Did you read my post above? It's not "clamping the trouser snake," it's gently compressing the urethra. If it's uncomfortable, you're using it wrong.
Which brings us to the point: How can you condemn something that you haven't tried, and that you're imagining using completely wrong? It defies logic.
If someone posted about how they'd never put on a diaper, but looking at them he could tell that they're uncomfortable and ineffective because they're not even the shape of a person, and they can't possibly work because the urine will just roll off all that plastic on the outside. Don't you think you'd point out that the diaper needs to be unfolded and put on correctly, and when it's worn properly it can be a very useful tool for helping to manage incontinence? Yet in this thread, we've heard all about how these clamps are painful and how their unethical manufacturers are preying on the hopes of incontinent people to make a buck, all from people who don't realize that they need to be put on and adjusted correctly, or that when they're used properly they're comfortable and effective.
Let's not forget that the idea of being incontinent is horrifying to most people. Studies have revealed that many people who aren't incontinent say they'd rather be dead than unable to control their bladders and bowels. Yet those of us who actually deal with incontinence on a daily basis realize that it's not the end of the world, that with the right tools and the right attitude it doesn't have to limit what we can do, and it does not have to define who we are. Just because lots of people are horrified by something doesn't necessarily make them right.
I'm not meaning to pick on
@parcelboy2 in particular - his just happens to be the post I responded to. This thread has dozens of people condemning something they've never tried, based on a misunderstanding of how it's supposed to be used, to the detriment of people who might actually be helped by it.
