For me, its simple, as many of people in MG just speak spanish, is common we like easy info, less work is better.
Others maybe like me just fail in believe what he said, because its difficult to doubt when you cant access to Japan information..well, we can access but cant understand. Also in that period of time, there was a lot of info being generated. Maybe if you dont work, youre out of school, etc.. you can get enough time to be in full with that.
But what I THINK is the main reason, maybe as a LatinAmerca characteristic, most of the time we believe what we receive, we dont take the time or the initiative to search or verify the information. We accept the first we get. Maybe Im wrong.
Most of the time I search info in what Im interested. About Macross i have interest, but maybe not enough to look in other places, there was the info I want.
