99% of marketing and television shows are aimed towards white culture and white people anyway
While probably true, It is almost just the title "White television" that screams "This is a channel for racist people" to some people. When you think "Black power" and "White Power" White power is almost always thought of as a racist slogan, while Black power doesn't really have that "racist feel".
and I'd say it is because of actual White Supremacists shouting that all the time, but I gotta say, "White Might" or "White Strength" etc. would bring about the same feeling.
There really isn't a single white "culture" though and that might make it seem worse. Like when you say "Irish power" or "English power" it starts to sound significantly less bad.
Though I notice that a lot of people don't like it when a white person refers to themselves as part of one of these cultures. Instead opting for thinking NO YOUR A WHITEY.
Edit: Maybe this is because I live in the US? and you can't say no I'm not <insert race/color of skin/genetic origin here>, I'm American without sounding like a moron...
