When first put to a vote, every single constitution delegate all originally voted against the bill of rights and John Adams didn't want to include a bill of rights at all (nor did he want to write one, Patrick Henry scared the hell out of him into including it). It wasn't until the threat of a commoner revolt (Shays' Rebellion aftermath (where private bankers hired a militia to kill American farmers, who were getting foreclosed on)).
Please remember that the US constitution is a slaver's document written to enable minority rule of slaver states at the expense of everyone else hence why it took nearly 80 years for the first republic to utterly fail and make way for the better second founding.
