You’re right, your obligations are between you and G-d and none of us have a right to an opinion. That is if you keep your thoughts or actions to yourself, but you put a serious topic out on a public forum and in a really inappropriate way, that makes it open season on opinions. Sorry that we didn’t all laugh, it wasn’t funny.
I see. Is that your best response?
I think you really need to let this one go. It wasn’t funny and I don’t think you ever meant it as a joke, otherwise you would have just apologized for offending people and let it go. Not one person on this thread is laughing with you. Give blood, don’t give blood, it’s your prerogative, but to come out on a public forum and keep defending a position that people are telling you is offensive is babyish and you might need to look into counseling to help you figure out social cues. Giving blood or not is a choice and you are absolutely free to make your own choice, but you’re not free to make offensive comments such as – “bloodsucking jews”, “you can all go to blazes” “I’ll mix it into my own blazing matza” without expecting some backlash. Dude, you’re not funny.
