A former radical jihadist related that it's almost a "running joke" that many terrorists "just need girlfriends."

"I'm not trying to minimize it or lighten it," Mubin Shaikh told "Fox & Friends" on Saturday. "The reality is is that it's because of nature and nurture. ... Hate is something taught, is something learned, and it can be unlearned."

"You see this across the board whether it's you know, white supremacists or jihadists, hyper-masculinity," he continued. "This idea that this is what makes you a real man, to be violent, to kill, kill in the name of God on top of that."

Shaikh's comments come after a van careened through crowds of people Thursday in Barcelona, Spain, killing 13 and injuring over 100. Later another car attack in the same city killed one. The Islamic State claimed responsibility for the attack and the number of attackers remains unclear. Several of the terrorists are on the run.

Shaikh added that there is also a "grievance factor" involved in terrorists' thinking since they may feel marginalized. The former jihadist said changing terrorists minds will require community social efforts, but that they should be caught, prosecuted, and killed if necessary.
