A blow against free speech at Oxford

Just read this article at Vox on how a debate about abortion at Oxford University was cancelled due to protests.

I’m pro-choice but I think it is deplorable that people should try and stop a debate on an issue. The person who got the event cancelled said:

The idea that in a free society absolutely everything should be open to debate has a detrimental effect on marginalised groups. Debating abortion as if its a topic to be mulled over and hypothesised on ignores the fact that this is not an abstract, academic issue.

How appalling. By her logic we should not debate immigration, welfare, or pretty much anything because they are not abstract academic issues. These are the issues we should be debating.
