The story is about the controversy surrounding the club. “New club starts after school, kids have fun” is a story that would only run in the schools newspaper. Outside of that it’s a complete non story.
So of course they are going to report about what the people who are protesting this are saying about it.
Additionally, the “advertisment” was really just a clarification on the point by ASSC that they only go to schools where there is another religious club.
This is a very neutral article just reporting the facts, you had to try very hard to be offended by it.
