Well, their methods certainly attract attention and debate, - more than most churches do!
Conversely, the 'controversy' Freedom creates and the publicity they get makes it quite an attractive proposition to some.
I'm sure many/most that attend are very genuine people but throw enough mud, some sticks and they will be labelled as something they probably aren't.
I'm just grateful we live in a country where we can still choose what religion, if any we follow, without fear of oppression.
If Freedom are a little shady, they fit in well with most Councils, many large and small companies and political parties!
