By "press" I mean mainstream deliverers of news - Fox, CNN, NBC, ABC. Personally, I don't think news delivered with the purpose of benefiting a political party is good for the people. Good for the party perhaps, but not the people.
Of course, it's not, but what you must also understand is what bias is and how it works. Bias doesn't mean that you favor one side of an argument over the other. It means that you favor one side of an argument over the other for reasons above and beyond the pure and simple fact that one side makes more sense.
Journalists are human beings. They are American citizens. Some of them are wealthy, but most of them are middle class at best. They pay taxes just like you, they have families just like you. They pay mortgages, rent, and medical bills just like you. They send their children to schools, they have student loan debt, they have friends and family serving in the military. They go to church, they drive the same roads, they celebrate the same holidays. They fear terrorist attacks every bit as much if not more so than you do. They worry about losing their jobs to technology like the internet. Some are east coast liberals, many were born in the heartland.
Their concerns in life are really not that different than your own concerns in life. There is no rational reason for the vast majority of members of the free press to prefer one political party over another unless that party truly is better for themselves and their country as a whole than the other one. These people have to deal with the endless spew of information coming at them from the world on a daily basis, and they are well equipt to tell you who is lying. So when the vast majority of the free press is taking liberals side and making Trump out to be a piece of **** you should be considering the possibility that they are telling you the truth, and he really is a piece of ****.
If 9 out of 10 Dentists told you that Crest was a good toothpaste and then one random Dentist told you that brushing your teeth was for suckers and you'd be better off using Mountain Dew as a mouthwash you'd be a moron if you listened to that one dentist. Unfortunately there's a lot of stupid people in this world that don't like brushing their teeth, and as a result, they're sadly likely to listen to the one Dentist who is telling them what they want to hear.
If 9 out of 10 mechanics told you that you badly needed new breaks, and one random guy told you that you're fine for another 50,000 miles you'd be an idiot if you didn't get your breaks fixed. Unfortunately breaks cost money, and as a result, there's a lot of stupid people in this country who would convince themselves that the one jack ass telling them what they want to hear is the good mechanic, whereas all those other guys are just trying to bilk them for more money.
The same thing is true about the press. If 9 out of 10 journalists are telling you that Trump is a narcissistic egomaniac that's lying to the country and destroying our Democracy you should try listening to them. They have no valid reason to want to undercut a president who is actually doing a good job of improving the nation. If you're trusting the one network that's telling you the things you want to hear contradicting all the others because it makes you feel good, then you're a moron, and you're getting scammed.
