George Costanza's political stature just keeps growing. Former Seinfeld actor Jason Alexander has taken to Twitter to voice his stance on gun control, noting that the weapon on the Dark Knight massacre was "a military weapon. Why should it be in non-mil hands?" After that prompted online debate, he offered a lengthy follow-up attacking "absolutists," or "ideologues" who think "they hold the only truth, everyone else is dangerous. Ever meet a terrorist that doesn’t believe that? Just asking," he wrote, according to ABC News. (More George Costanza stories.)
