You're the only one policing here. You got something actually meaningful to add besides the fact that you don't like my opinion?

How about this, I'll respond to your comment too.

9/10 that color is brown and yet call someone colored...oh no he didn't.

First of all, words have meaning and connotations. In spanish "negro" is just a color, in english it's not. You can describe someone as "a person of color", you can even describe them as brown or black but "colored" has a negative historical connotation and so we don't use it. It's really not rocket science.

There's nothing wrong with describing someone as non-white. In this case /u/book_hoarder does it anyway in a stupid, round-a-bout way despite not actually knowing the ethnic background of any of the people at the wedding in question. It would honestly be less idiotic if she just said they were "people of color" instead of trying to allude to it by describing them as "Mexicans" or "spanish speakers".

You can point out someone is not white, it's not racist. You can't call someone "colored" because it has racist undertones due to its historical connotations. Are you following so far?

we are all colors if you want to get right down to it.

We are not "all colors if you get right down to it". Racism is real and being cOloRbLInD isn't an adequate response to it. Grow the fuck up and stop pussy footing around the issue. White supremacy is real, and it isn't any less real just because you're afraid to address it. Spending your time making sure everyone knows how not racist you are isn't going to make racism go away. And no, pointing out/acknowledging racism doesn't make me "the real racist".
