I have noticed that when non muslims are trying to come across as liberal, tolerant, and respectful of islam, they usually make a distinction between 'good' muslims and 'bad' muslims.
In making this distinction, they think they are arguing that the 'real' Islam has been hijacked by extremists with the wrong interpretation. They feel that they are defending Islam from disrespectful Islamophobes. But the distinction they are actually making is simply one of religiosity: - Good Muslims are those who aren't really Muslim.
They dont realise it, but they are actually saying that they really do not like Islam.
For example, this girl is distinguising between Muslims who go down the pub and drink, and Anjem Choudary:
