Realistically is it better to dual wield swords or would just a single sword be better assuming this is an average person off the street?

I am a Black Belt in Hapkido, Taekwondo & a few others I've also Boxed Taekwondo Contrary to popular belief it is one of the best martial art's to learn if you ask me , most people might be "effective" with other styles but its because of there skill level I would say, I could beat a person souly with Hapkido, with Pure Takewondo, With Pure Judo, or pure boxing in a Fight its because I know how to Utilize it in a fight Street fight or MA- Based Fight. Depends what you are trying to do or what you want to know. Taekwondo is Good if you want to do Tournament look up ATA & WTF If its self defense you are after I would recommend taekwondo But also Another martial arts close (Boxing as well if you can find a good gym).

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
