You've just made it even clearer that this comparison doesn't add up. The underground railroad was legitimized with the fugitive slave act. The more you try to force this comparison, the more obvious it becomes you don't have any idea what you're talking about. The US civil war and the problems with Israel and Palestine have little in common. Support for Palestine isn't support for Hamas. Hamas barely won the election that you're hinging your braindead takes on, the PLO and fatah still exist and would be much better options than Hamas, and between the two of them have more popular support among the people of Palestine. Israel is a fascist, apartheid state with dubious claims to the territory they occupy. They hide behind Judaism to justify their war crimes and actively promote antisemitism to conflate support for Palestine with said antisemitism. You're falling for their propaganda hook, line, and sinker.
