I can understand why answers with a low score have a button to vote for deletion on normal SE sites, but I don't think that's appropriate on Meta sites.
Answers and votes on Meta sites don't have the same meaning as on normal sites. They're clearly more opinion based, and a negative number there simply implies that a number of people disagree.
I'll take this example on Meta.SO. It currently has +7 votes and -15 votes, adding up to a score of -8. It also currently has 2 deletion votes (1 vote away from deletion).
Firstly, I don't think it's right that answers with a negative score should have their text made harder to read on Meta. It's not because 2/3 of people who've read this answer so far disagree with it that the points made in such an answer should be harder to read. (Being at the bottom of the list when order by score should be punishment enough.)
More importantly, does any of this warrant deletion? This answer isn't offensive. It simply represents an opinion that something between 15 and 17 people (the 15 who've downvoted it and possibly another 2 who've voted for deletion) don't agree with, as part of a wider discussion (7 people see to rather agree, since it was upvoted).
Deletion of low scoring answers on normal SE sites generally make sense because these answers are generally misleading or of poor quality.
Doing so on Meta is just rude towards the answerer who took some time to consider the question and suggest an approach to solve the problem. It's just censorship, at this stage.
Could we please have all answers with the normal font colour and remove that "delete" button, on Meta?
