You do mean until Wednesday night. If you're in Israel, you can post tomorrow night as Pessah in Israel lasts only seven days; outside the Land Of Israel its eight days.
By the way, as for the HP post, the guy must be a 9/11 Truther. We all know THAT was all the Jews' fault and that is why sanctions must be imposed upon Israel and American Jews must be forbidden to support the Jewish State. I would think his point of view would also go after every one else who supports Israel. At least I still have the freedom, thank G-d, to say I'm with Israel!
