That is too easy.
What you fail to understand that being a member of a protected class does not grant you special rights.
If you are gay, that does not mean you can demand a political or terrorist type cake can be made for you. It just means that you have the same rights as everyone else.

Every person is a member of a protected class, think about it.
Here are some protected classes in Colorado:
Race, Color, Disability, Sex, Sexual Orientation (including Transgender Status), National Origin/ Ancestry, Creed, Marital Status, 

Every person is a member of at least one of those. That does not grant a person any special rights.

So, your gay KKK guy does not have some special right that grants him the ability to force anyone to make political or as you call it, ‘terrorist’ type,  pastries or baked items.
