I do not trust my subconscious mind; society has placed too much junk there. Society has placed many negative assumptions about race, gender, class, sexual preference, appearance, age, weight, disability, language, job, religion, etc.
I do not believe it makes you a bigot to be aware of many bigoted stereotypes. I do not believe it makes you a bigot if sometimes these bigoted stereotypes pop into your head. These thoughts are, after all, not your own, unless you choose to own them. Society has been planting them in your head for your entire life, and you really can't help it if you are aware of the negativity placed there. You must only rely on your conscious mind to recognize, understand, and resist all the assumptions society has planted in you.
We have all these assumptions about all sorts of things. We consume this culture whether we want to or not, and this culture contains negative stereotypes about race, gender, class, sexual preference, appearance, age, weight, disability, language, job, religion, etc. We must always try to weed this junk from our conscious thought, and be aware of this junk in your subconscious. But it's always going to still be there.
