Because blackcurrant is disgusting

INCORRECT. Blackcurrant jam is best jam.

DOUBLE INCORRECT: blackcurrant is terrible and I am correct. I will say it's not the worst offender, orange marmalade is probably worse.

You're just broken and wrong and your opinion is objectively wrong. And now I shall hide in a knife-proof shelter.

How are you going to spread your jam in your shelter if you can't take a knife in?? HA! QED.
