True, but the question is whether those who do intermarry are extended full rights – which, according to Haaretz, they are not:

Israeli law does not permit marriages between members of different religions within its borders.

The article goes on to say:

…an interfaith marriage in Israel means that at least one spouse is defined by the Interior Ministry as “without religion.”

There must be an acknowledgment that the “marriage equality” extended to Palestinian non-Jews (and indeed, anyone who does not fit the halakhic definition of Jewish) seems to only exist on paper.
