Very true, I suppose nobody can help you if you'll just blindly believe whatever you read, regardless of source, but particularly in the case of tabloids. But I do think it is scary and irresponsible of the media to act like this, as it changes the framework of issues and the way we look at the world.
Take two of the recent terrible atrocities that have taken place - the church shooting in the USA, where lots of black Catholics was killed, it is heavily emphasised that it's a lone, mad gunman acting on his own.
The Tunisia shootings of tourists has been reported in the Sun this morning as 'Us against Them', with words like Islamic militants, ISIS, Muslims, terrorists, jihadists.
It helps frame the story's where one isn't a white supremacist attack on a black church, inspired by race hatred. It's an isolated nutter. Whereas the other is framed as a whole religion's attack on us and our way of life. Rather than some lunatics with machine guns or any other way that the story could be framed. (not saying any of the above ways is the right way to frame a story, just point out the difference in reporting).
