Here's an extreme example to make something obvious:
1000 people are stabbed to death every year in Country A.
1,000,000 people are stabbed to death in Country B.
Which country are you more likely to get stabbed to death in?
You cannot answer that question without knowing the population of each. By laughing at "rates", you are taking the position that the numbers of people living in each country are irrelevant to the likelihood that you will be stabbed in that country. Let me show you why it is nonsense:
1000 people are stabbed to death every year in Country A. Country A has 100,000 residents.
1,000,000 people are stabbed to death in Country B. Country B has 1,000,000,000,000,000,000,000,000 residents.
This means 1 per 100 people get stabbed to death in Country A. 1 per 1,000,000,000,000,000,000 people get stabbed to death in country B
If you say you are more likely to get stabbed to death in Country B, this means that you are angry at things like numbers and mathematics, but don't know what they are. You see, in this case, you're running a notable risk in country A.....but you could be expected to live in Country B for many many many times the life of the entire known universe without getting stabbed.
1000 people are stabbed to death every year in Country A. Country A has 100,000 residents.
1,000,000 people are stabbed to death in Country B. Country B has 10,000,000 residents.
Now it's 1 per 100 people getting stabbed to death in Country A, but 1 per 10 people getting stabbed to death in country B.
