if it were an "allegation of fact" then it would be an opinion, so your question is disingenuous.
If something is a fact, it is a fact, there is no refuting it, it simply is. If it is an opinion, we can have all kinds of fun and intersting discussions.
Now we can see what your ultimate goal here is. If I claim it is an opinion, you will go off on your ad hominem attacks about how I'm not worthy of expressing an opinion, and you are above such lowly thoughts, and no one should ever listen to me.
If I claim it is a fact, you will then try to prove it is not a fact, but an opinion, thinking you have "gained one" on me by dissing both my opinions and my view of what a "fact" is.
So really the question is an extened ad hominem attack, which I don't think adds anything to the discussion.
The only real question is, do you want to actually discuss safety and the roles of law, inspectors, and unions in saftey, or do you not? Because sofar, you have not done so.
