Legislation prohibiting the boycott of Israel in 26 states in US !

I remember back after the hurricanes devastated Texas, that there was a clause in the FEMA aid package that you had to sign, saying that you would never criticize or boycott goods from Israel.
Well now I know that this legislation has been passed already in 26 states, & is pending in 13. Wow, if this doesn't make you concerned, then I suggest you look into the Palestinian & Israeli situation & its long bloody history. A lot can be understood & groked in full if you also look up the history of the Zionism...
