Howdy Dan; No, the Israeli Interior Minister Roni Bar-On was not referring to free speech. He was referring to MK Azmi Bishara and other Balad MKs 1) violating an Israeli law which prohibits MKs from visting countries which are still technically at war with Israel without permission, 2) publicly expressing solidarity of the Arab Israelis with an enemy state, 3) encouraging Syria to continue its "struggle and resistance to the occupation" thus inciting others to violence, and 4) warning Syria of a theoretical and immanent attack by Israel (which is highly unlikely) thus increasing tensions. Free speech is not a free pass to break the laws of one's own country nor to flagerantly commit the crimes of high treason, sedition, or incitement to violence with impunity. MK Bishara can go ahead and exercise "the rights of Arabs in Israel to maintain relations with Arab nations" as much as he wants to, but he also must take the consequences of doing that inappropriately and illegally.
