It's not necessary to be sarcastic. The media is well known for being usually unfair and bias. A lot of hatred towards other groups is due to propaganda. It has been like that for a while.
That specific well has been visited a bit too often, IMO. Media is of course not reliable, but it is not unwilling to show diverse perspectives either. They have a fierce internal competition, after all, and need original messages to show.
And, of course, about one person in five in the whole world is a Muslim. One would expect bias to fly only so far. Or at the very least, to actual examples and counters to the bias to be easier to find.
Often we end up having to take on faith that there is a nearly all-powerful conspiracy of bias against Islam, with hardly any evidence to show for it. At the same time we are also invited to gloss over Quranic verses that talk about keeping infidels and women in their proper places, apparently just because or supposedly because God wants so.
And now and then, we are reminded that "there is no compulsion in religion", an odd verse that apparently no one feels entitled or capable of actually interpreting or explaining. It is presented almost as a mystical evocation, self-sufficient and with no need of connections to anything else.
So no, I don't think the appeal to media bias holds any weight any more. Not by itself, certainly.
