1. Person X wants attention to their manifesto.

2. Person X becomes a terrorist for that purpose.

3. People say "Y'know, because of all those terrible things X did, I took a look at their manifesto, and they have some interesting ideas."

4. Person Y sees this, and repeat.

Suggestion: When people actually care about ideas, there are plenty of thinkers they could read and talk about, without encouraging future terrorists.
