Facebook I hate cyclists group infiltrated!

Are you saying that I have no right to mess with anyone's employment or is it this case only and where do you draw the line?

If someone was on the net saying that they were a teacher and hated kids and implying that if they weren't covered head to foot in a burqa he might well sexually abuse them then I would argue that anyone who did not report that person was scum. I hope that you would agree.

I am not sure that expressing the opinion that you hate cyclists and implying / saying that you don't care about their safety and implying / saying that you are a shit driver is much better.

You can't just sack someone because of their opinion. He would only get sacked if the boss thought it was right AND had a legal basis to do so. Most expressions of opinion would carry no risk of being sacked, it is only in extreme cases where the risk lies.

You can only get to the idea that he doesn't care about their safety by stretching his words to an extreme. What he actually says is that if he crashes taking evasive action to avoid a cyclist, he'd like to be able to claim on their insurance, although he says it inarticulately and dressed up in hyperbole and bluster.

But you'd much rather take offence so that you can get all riled up and join an internet lynch mohat he actually says is that if he crashes taking evasive action to avoid a cyclist, he'd like to be able to claim on their insurance.

BTW, your hypothetical example is just as much a hyperbolic exaggeration as anything that the bloke published on Facebook, and about as honestly-intended a question as "When did you stop beating your wife?"
