No, it is you that is wrong, as usual. Severability in contracts is not the same as severability in legislation. Look it up. :lol:
From Wikipedia:
Severability
. . . Severability clauses are also commonly found in legislation, where they state that if some provisions of the law, or certain applications of those provisions, are found to be unconstitutional, the remaining provisions, or the remaining applications of those provisions, will, nonetheless, continue in force as law.
