In what respect? Are you suggesting that that the respondent's line of thinking was not their own?
Yes, in that almost all of those critiques are based on how Corbyn (or Labour) was reported rather than individuals reviewing and assessing of the circumstances. Look at this bit for example:
Most people who themselves like or dislike something are able to articulate why reasonably -
this cake is too sweet, this bath is too hot, I like how economical this car is etc. Look at that selection though - they dislike Corbyn, but no-one gives an actual, individual reason as to why.
What we are left with is, basically, reflections of the media and political campaigns against Corbyn run between 2015 and 2019. He isn't a good leader (even though if you ask most people to define what makes a good leader, he'd probably up ticking more boxes than other politicians); he (or Labour) aren't credible (which begs the question - credible to who? This is the old electable argument); he's proved himself totally unfit to govern (based on what, exactly?).
