<p>Ok I’ll try this approach:</p>
<p>Denying the holocaust is probably not allowed on campus. Why? Does it hurt anyone? Besides some feelings? Even if you do it for practical reasons - say an archeological study. It’s just something entirely related to events in the past.</p>
<p>However, if I were to complain that a communist group hurts my feelings, also based on past events, no one would care.</p>
<p>That is my only problem. My hatred is being discriminated.</p>
