If you don't know the holy handgrenade quote, just enter holy handgrenade in youtube and all should become clear. It is a joke.
You, otoh, mention things that raise several red flags.
I don't know you and perhaps you posted those comments as a private joke, or maybe there is a whole lot of context that might make those things make sense. But we see plenty of people come and go, who say things similar to you, and who mean it. they blabber on about secret ninja masters, special powers, bizarre rituals, etc.
If your swords are important to you in a religous way, I am not the person to make fun of it. There are many people here whose beliefs are way outside mainstream. But if you mention things like walking patrol with your sword, naming them at full moon and listing something metaphysical as your art... you should be able to see that this comes across as weird. Especially if you don't give us any more information than that.
