I felt much the same way for years but what turned it around was a simple check into the terms of service agreement. What I read is this which is part 'h' and part 'i' in the acceptable use policy found on their website beginning-You may not use the PayPal service for activities that relate to sales of: (h) ammunition, firearms, or certain firearm parts or accessories, or (i) ,certain weapons or knives regulated under applicable law
Our normal dealings do not apply because what most of us sell is not a 'regulated' item under law.
What I read is that PayPal is no more "anti-gun" than they are "anti-smoking", or "anti-drinking" just because they also decline to permit transactions in tobacco or alcohol products which obviously are regulated items. Basically they don't do much different than most of the places we deal with for anything else. You can't blame them for protecting themselves legally here or for wanting to protect their members and thats basically why they have these limitations. I don't see it as reading they are anti anything so much as they are just legally covering their own behind. Reading the acceptable policy they also don't allow selling of third party info and other such things all relating to regulated items or things such as gambling but I don't see that as meaning they are anti gambling either. Chances are that many of their employees shoot actively, own and carry knives, gamble and drink and smoke.
Besides all this I've found pay pal to be invaluable to me for international transactions making it very convenient to not only be paid promptly but convert currency to US dollars or the other way around should I be the buyer.
