well it wouldn't be hard to know about them if it was your church that had the signs vandalized or if you drove by a church and seen their signs vandalized..

If the tables were turned and it was a Christian sign that had been vandalized and made national news then it makes me wonder if your thinking would be different. I wonder if you would think that it was the Christians themselves that vandalized their own signs??

When you think about it what better way to gain more news coverage and publicity than to make it seem like the opposing side destroyed your sign and not to mention make Christians look like hypocrites.
