The world as it is today is skill-driven. You generally need skills that can be used in a workplace to get a job, and not just your college degree The world has changed rapidly. Ultimately, everyone is going to work in the private or public somewhere and both of these places have the majority of the jobs that fall into categories like;
Engineering, IT, CS, Data Science, Architecture, urban planning, coordinating, Hiring, staff, organizational— HR, counseling, learning, training, Management and finance
If you have a degree in philosophy, you don’t fit into any of the above categories. You do not have any skills that are actually usuable for a company. All of the jobs above are generally skills based. What skills do you have as a Philosophy major that could be used here? Almost none! Which might render you valueless. So if you get a degree in English or Philosophy or other majors that are not skills driven, then your only hope is academia. For academia, you generally need a PHD. If you just have a bachelor’s degree, you generally can’t even teach high school.

It depends on if you don’t want to date black people because dark skin or a certain physical feature turns you off sexually, that’s totally understandable. You have no obligation to date someone who doesn’t satisfy you. That’s not racism—as long as you have specifically determined you don’t want to date each black person you meet because you’ve evaluated their traits and make sure to consider black people as individuals and not as a single entity.
If you don’t want to date black people because you feel they’re inferior to you, or you think they have a personality trait you don’t like, or something that you ascribe to their entire race as if they’re some kind of hive-mind clone entity, that’s racism. Racism is ascribing— usually negative— traits to an entire race or viewing an entire race as inferior to you.
