For the sake of argument, let's compare this with the Code of Conduct for the British Computing Society, a professional organisation for IT.

Public Interest

You shall:

a) have due regard for public health, privacy, security and wellbeing of others and the environment.
b) have due regard for the legitimate rights of Third Parties*.
c) conduct your professional activities without discrimination on the grounds of sex, sexual orientation, marital status, nationality, colour, race, ethnic origin, religion, age or disability, or of any other condition or requirement
d) promote equal access to the benefits of IT and seek to promote the inclusion of all sectors in society wherever opportunities arise.

Clearly incompatible with being a racist. If an institution for chartered professionals can clearly state "don't be a racist", I think a conference could do the same.
