Yep I believe it will be. The cool thing (I think) about go fund me is that all donations are anon. So people don’t have to catch a ton of flack for giving to causes they actually believe in.
If I knew for sure and certain the $ raised would be accepted by the Trump admin and used for wall/fence I would donate a small amount (small since I am dirt poor) but I’d have to have Trump say something about it, that they will accept it.
