You stated that only half the body bags were opened. You completely made this up because it doesn't say that in the BBC report at all. You have no idea how many were opened. You also ignored the fact that the report opened with a mass funeral of a further 20 bodies. What do you think would be in unopened body bags anyway, potatoes? You can't really expect them to have the full body count on display for the BBC. Families tend to want to bury their dead or look after them themselves.
You also used "men of fighting age" line to try to legitimise the attack. That is not evidence. You ignored the fact that women and children were killed including a two year old, and you ignored testimony from an injured young girl stating that "there was no military camp. We were just living there". Whether it was 50 people or 85 is not important. What is key is that there is very clear evidence of many civilian casualties and zero evidence that this was a legitimate target.
When this report was filmed the building was still smoldering. Libya seems to be relatively open in terms of media access so if there was any evidence of this being a legitimate military target the right wing media would produce it. They haven't. So any logical and unbiased person could only come to one conclusion on the evidence presented.
