I also want to become someone like that, especially the way of thinking about the western culture, "law suits."

"When there are fights or law suits in the north, I'll say, "Stop it.,

Bbecause it's not important."

Every Japanese person has been becoming more selfish day by day, and demanding their right, without doing their duties.

The ex-US president JF Kenedy Konce said in his statement, which was close to the traditional Japanese way of thinking, I guess.

Either write his full name (John Fitzgerald Kennedy) or just use the abbreviation JFK.

Never say "has" before "becoming" without "been"

The ex-US president JF Kenedy once said in his statement, which was close to the traditional Japanese way of thinking, I guess.:

Chiristians have learned the spirit of volunteerism in church or byfrom the Bible.

you can say "learn by reading" but if you talk about a specific source we always say "learn from + X"
if you say "by" the next word should be an action

So they are becoming more selfish than the wWestern people who have their religious restrictions against selfishness.

When talking about Western countries & society, you need to capitalize

Hot Dog-san, this is an interesting quote, but you didn't explain who said it.

Because it's not important."

Combined with the previous sentence.

Every Japanese person hais becoming selfish day by day, and demanding their rights, without doing their duties.

I miss the Sowa Era from this viewpoint as well.

However, Japanese people don't have theirare not religionus.

SoIn a sense they are becoming more selfish than the western peoplepeople in Western society, who have their religious restriction against selfishness.
