Groaner, I agree but, stating what appears to be a fact and then claiming it was only an oppinion after the fact is not quite what I meant.
If I was to state "I didn't like that flight with X airlines, it didn"t feel safe to me" or "I thought Y airlines aircraft looked a bit old and ratty" surely you couldn't be crucified for that.
...and what if X actually is a convicted paedophile? Is stating a fact illegal? That would be a worry indeed as are these SLAPP things
