I live in the same country as you. The reason why there are two different perceptions even though they are both gambling operators is because of the nature of the gambling they operate. The nature of the first one, which is the lotto outlet, is supported by the government. Meaning, that it is being promoted in a good way and even included in the television newscast to inform the citizens about the possible amount they can win.
While in the cockpit fight, you can never hear any good news about it. There are even some people who have gone missing or found dead because of it. Some people even say that the men of most families in our country who are into cockfighting are much more concerned with their rooster than their own child.
i agree with you. compared to lotteries, cockfighting gambling seems more cruel, inhumane, rude, and sometimes there are cases where players or bettors are cheated by operators. and because of this, people's views on these two types of gambling are quite different, even though both of them also offer services that can be fraudulent, but because the lottery is promoted in a good way and appears to operate more cleanly, people's views on it are better.
It's true that the way people choose to present and promote a gambling activity can actually have a enormous influence on how people view and perceive it.
Both cockfighting and lottery are both Gambling that can have almost effect on the gamblers involved but lottery gambling is often promoted as a fun way to potentially win big prizes, while cockfighting on the other hand is often associated with violence and illegal activity. And just as you mentioned, both gambling activities could have negative impacts on the life of the gamblers.
