Why Filipinos always tell negative things about their countrymen? Is that a crab mentality?

No. Nothing wrong with saying negative things. A lot of Filipinos dont understand the concept of "Crab Mentality". Crab Mentality means "pulling someone down TO PUT YOURSELF ON TOP" REPEAT: "...TO PUT YOURSELF ON TOP" Even if, for example, I criticize the Philippine President (Pnoy), as long as I'm not doing it to raise my own status, then no, that is not Crab Mentality. For example, you have a friend who's breath stinks. You tell her, "Hey, buddy, not wanting to insult you but your breath smells funny." That is not crab mentality. You were just meaning to save her further embarrasment or You see a co-worker sleeping in his job, and you tell him, "Hey, Dont sleep. Were all getting paid to work." Again that is not crab mentality. You were just telling him to Do his Job or You see a man covered in Sh*t, and you were like, "EEEEEEEEEEwwwwwww!" That is not crab mentality. You were just stating the obvious. or you watched a movie and you werent satisfied and you were like "That movie was a waste of time." that is not crab mentality. Everyone is entitled to his own opinion. Please, I see this the most on Pnoy's supporters. Whenever someone criticizes their beloved president, they accuse that person on being "Talanka". But they, in turn, are very quick to judge the former President GMA. Just stop, people.... Anyway, Back to your question- Again, Saying negative things, as long as you don't mean it to raise yourself, is not crab mentality.

NO. It is called every ones mentality..........human mentality. Not only Filipinos but in every race, where you came from is not an exemption.

Yes that is crab mentality. That's one major reason why the Philippines can't grow economically.

ever seen crabs in a bucket? for some reason, the crabs inside pull the ones on the top of them so that the ones below and on their same level will never get ahead. that's how most Filipinos think when someone suddenly becomes popular regardless of how they got there. there will always be idiots who will do anything (telling negative things is the least of them) to make the ones in a higher position look bad, not because those idiots want to critique, but because those idiots believe it makes them look good so that they can be in a better position to move up the ladder, so to speak. basically, crab mentality is the mindset of pulling people down so that no one gets ahead of anyone. it's always the case that the person being pulled down is that much better than most. it's a pathetic Filipino trait born out of jealousy.

And the truth shall set ye free. Rejoice!!!

filipinos in general are negative thinkers, crab mentalists, utak-talangka, mapintas, putting the blame on others, fault finders, and reason benders, but again, its the culture that never changes

It is just Filipinos who are bashing Filipinos, it is everyone. The difference is Filipinos recognizes how awful we are, and we talk loudest, some have no shame in fighting in public amongst Filipinos over silly things, control everything, everyone wants to be the LEADER.

There are more negative things about Pinoys than positive things I guess.
