Because I have an apostrophe in my last name, I attempt a SQL injection attack every time I fill out a form. The RSA conference is aware of this, and requires everyone who has an apostrophe in their last name to stand in a separate line. Apparently they have not yet learned that it is possible to secure a webapp against the dreaded ' without blacklisting the content.
I find this to be equivalent to segregation against those of us who have apostrophes in our name, and by the principle of transitivity, RSA is attempting to segregate out the Irish without posting an "Irish Need Not Apply" sign. Mark my words, first they will come for our crypto keys, and then they will come for our potatoes.
