Unfortunately it is not "simples", nor has it been for some time.
Why are these people "flying the flag" whilst protesting outside a mosque?
What about these people?
How about the use of the English flag here:
Is it to signify support for traditional English values such as setting fire to buildings with people inside them, or attacking the police?
If you don't see how a movement with disgusting, hate-filled, violent, ideologies has hijacked "flying the flag", then either you are incredibly naïve or you share those ideologies to such an extent that you see nothing wrong with them.
