"If you're an academic, you will certainly know that if you made that comment in a scientific context, what you said would be exactly the kind of inaccurate and misleading representation of the evidence that would get a thesis sent back for a rewrite."
If it was an academic paper, it would be sent back for a rewrite, yes. You are entirely correct there. But those theses will be published by the university, and the reputation of the university might be harmed by endorsing a poorly-written paper.
A seminar is different. It is a much more casual atmosphere, and it assumes anyone who entered the room read the relevant materials, is there to discuss ideas freely, and have a discussion about it. There are debates and criticisms flung around to encourage growth and evolution of the individuals and their ideas, but getting angsty over someone's choice of words is moderated. Usually, it is allowed for a person to explain what he or she meant or correct him or herself. If behaviour persists even though the person explained his or her position, they get booted and given a fail. To avoid being booted out, the person with an axe to grind should be able to demonstrate the ability to move on rather being obsessive.
There is a huge difference between having an appointed supervisor review the thesis or submitting it to a committee seated by several doctorates to read the draft before finalizing it; and having somewhere between 10 to 40 students seated in a classroom helping another student develop his or her thesis by hosting a public forum of discussion. So, don't assume the process in both settings are the same.
Last time I checked, none of this is going to be submitted to a journal or a magazine. It's only a discussion forum.
By coming to this thread, I assumed the audience is here to discuss what happened near Mackenzie, British Columbia and the possible factors leading up to the attack. Therefore, to me, the discussion is about bear attacks in specific, not the bear populations in general. So there is no need for me to be very specific with the way the sentence is structured.
So, yes, bear attacks are rarer than hen's teeth: most hikers know that and statistically is rarer than hypothermia, firearm accidents and felling accidents. If this is a forum where people are more irrationally afraid and believe in a lot of myths (and yes, I stayed in countries where people won't leave the house because a single lone wolf has been sighted 15 months prior amd it's really difficult to convince those people that it is oaky to go for a hike in the forest again), then I would write my sentence differently because the audience would be different.
