Except that's not what people are saying, is it?
People are pointing out that LC was sentenced in line with the guidelines for inciting racial hatred - a crime which she herself admitted.
People are pointing out that a guilty plea automatically leads to a guilty verdict, whereas a not guilty plea - as in the case of Jones - is less certain. This, in itself, is not "two tier justice".
People are pointing out the significant differences in these two cases between the charges and between the pleas that were entered. And they are highlighting the fact that these differences are highly relevant when considering whether or not there has been "two-tier justice".
People are stating that what Jones did said was reprehensible while simultaneously acknowledging that he was entitled to a trial under our existing legal system and that the jury in that trial - which examined all of the relevant evidence in more detail than we can on this thread - found him not guilty of the specific offence with which he was charged.
People are pointing out that a jury may or may not have reached a guilty verdict had Connolly chosen to take the risk of going to trial.
People are pointing out that, for all of the claims that Connolly was poorly advised, the evidence presented in her appeal did not support that.
Some people are stating their view that inciting racial hatred is indeed a serious crime which they believe warrants a prison sentence, and they are voicing their objection to the people who seem eager to minimise Lucy Connolly's crime.
