Not necessarily. But you should take things with a grain of salt. Like the local news saying that YWAM was specifically about converting Muslims to Christianity. It doesn't take much for a line to picked up and repeated without any real basis in fact. With 10,000 members, it's more likely that 7,000 is the total who attend on a weekend. Probably over 4 services or more. The shooting occurred after the last service was over (I believe). So, a guesstimate of the number on campus would be in the hundreds, not thousands.
I totally understand what you are saying. I just find it a little surprising that a member would castigate others for repeating in a post what has been published in thousands of articles.
My son is with YWAM in Australia and another fella at his base said his brother had been in Denver with Matt Murray and that Matt had assaulted his brother. So that might have been one reason he was asked to leave. Another person posted recently that YWAM goes the extra mile with folks and it would have taken alot for them to have asked him to leave.
