Logic is used when Logic is presented. If people start creating nonsense like this then "Sword" is the way to go.
Emotional and immature response which hinders dialogue.
1. If you were
baited by professional trolls (Bhensa, Tarq Fata, etc.) on social media, you should respond by ridiculing them. Create a parody account and troll them back. However, if you respond by threatening violence then you give them power over yourself. And, this is exactly the way they want you to respond, i.e., violence or "sword'.
2. Because you responded with violence, the news is no longer about blasphemy and the conversation turns from limitations of Freedom of Speech to, "You broke the law! You're violent!" You have essentially given more ammo to your critics and disarmed your supporters despite the fact that they were wronged and have a valid point, i.e., Bhensa broke the laws in the first place.
3. The "sword" has never solved any problems. If anything, you turn the freaks into martyrs. Look at Salmaan Taseer. It no longer matters if he was corrupt or a cheat, Qadri has turned him into a liberal saint and a martyr overnight. That's dumb in my opinion.
Putting logic and narratives aside, what bothers me about the "sword" argument is that we are told, from a young age, the story when Prophet Muhammad (ﷺ) was mistreated by an old women and he never responded to her. In fact, Prophet Muhammad (ﷺ) visited her when she was sick. Compare your response with this and two couldn't be more different.
I apologise in advance if anything I said was harsh.
