You have already made up your mind and are so deeply embedded into your delusional world. Trying to convince you would be a complete waste of time.
However, I'm clarifying a few things in case others who aren't familiar with FMA will not be deterred by your false statements about FMA.
Wrong mindset - FMA train for fights, not self defense. FMA were used during a time of war against the Spanish. The claims that FMA helped Filipinos defeat the Spanish during the Philippine revolution are exaggerated. If you study history, you'll see that guns ultimately helped the Filipinos win the war.
FMA focuses on drilling responses to various angles of attack regardless if it's an unarmed(grabs, punches, kicks, etc) or weapon attack(knife, stick, etc). That's why techniques in FMA are universal, meaning we apply the same concepts when defending against a knife or unarmed. This helps in covering more than one combative situation at a time because we are still moving like knife fighters even when it's not a knife fight.
Your premise of "Well the Filipinos had to use guns against their enemy who also had guns, thus FMA is useless", is filled with logical fallacies. You would probably be saying that FMA is useless if they lost the war. You seem to have you bases covered, you can't be wrong regardless.
In FMA, you'll hear alot of concepts like checking the hands and trapping or parrying then attacking. You might see them do something like this.
No, the concept is attacking you're opponent without getting stabbed to death. You have to deal your opponents weapon arm, that can be done by either disarming, controlling or revering the knife on them. If you are attacked with a knife and I focus on their non-weapon arm I'm going to get severely injured or more likely killed. That's why the parries, arm checks and de-fanging techniques are in there, you have to deal with the weapon first.
The problem with that is knife fights are completely different from knife attacks. Knifemen usually ambush you. By the time you realize what happened, you would've been stabbed or slashed repeatedly. These are some clips of how real knife attacks go down.
"Knifeman" must still use knife attacks to inflict injury. There are plenty of instances where people have defended themselves against knife attackers. It's a disadvantageous position to be in to defend yourself against a knife-wielding opponent, but I rather know what to do if faced with one opposed have a self-defeating approach and never training it.
No multiple attackers - Other issue with FMA is there's no training to deal with multiple attackers. Doce Parres was attacked by a couple of knifemen. He stabbed two, but got hit from behind with a chair. His attacker took his knife and stabbed him repeatedly. Doce Parres disarmed him back and stabbed him back before passing out. He woke up in a morgue because people thought he was dead. What was his mistake? Lack of situational awareness.
You're completely wrong. FMA schools work multiple attacker drills as well as spar one-on-multiple. You clearly haven't done any research into this.
Doce Parres is a system of Kali, not a person, thus I don't know what attack you're referring to.
In conclusion, FMA is not ideal for self defense. It's going to get you beaten or killed most likely.
No, standing around and pretending dodging a nerf gun dart is the same as a bullet from a firearm(on your YouTube channel) will get you killed. Waiving your arms around with no structure, speed nor power will get you killed(Your video). Teaching a self-defense class when you have no understanding of martial arts will get
OTHER PEOPLE KILLED. I hope you don't actually teach self-defense. If you want to exist in your own little world of delusion then only include yourself in that world, don't invite other naive/inexperienced into it.
