Mr. Anuran,
Your post indicates your lack of knowledge about the halacha and facts. You are assuming that our ancestors did not check for bugs. You have no reasonable basis to assume that, it is just your wishful conjecture. Most certainly they did check for bugs and thoroughly at that.
The gemara talks about certain bugs that grow from themselves. Poskim universally understand that to mean that the bugs were implanted before they are visible. And visible means just that. Many bugs, ceratinly those that are on strawberries and coppepods in water are visible to the naked eye even without magnification. You may need magnification to identify what type of bug it is. But that there is something there is clearly visible. Bugs in fish or fruit that were laid before they were visible and grew inside are not ossur. The question with the fish is because certain bugs or worms did not grow in the fish rather they were or quite possibly can have been ingested after they were visible and there is no way to tell.
To detirmine what is consistent, you would first have to understand the halacha, which you clearly don’t. And you have no basis to assume that my ancestors, and possibly yours as well, did not check fruits, vegetables and fish for bugs.
