I wouldn't become one because the hats look silly. But I look at it this way: If the gates of Hades can't prevail against the Church, then the gates of freemasonry will hardly be much more of a threat.
Well, to tell you the truth, it's not an issue that bothers me a whole lot.
I think about ten years ago, I got a letter from the Masons inviting me to join, I'm not quite sure why. I sent back a polite letter declining and explaining that I was a Catholic, and I never heard anything more.
That was the only time. On the other hand, I've had Jehovah's Witnesses come to my door and invite me to join five or six times. I feel sorry for them, because they believe that only 144,000 saints will be saved, and I suspect there are too many low-level door-to-door workers for all of them to be included in that number. If they make any new converts I'd think that would decrease their chances. Or maybe only the higher-ups in the organization will be saved.
