HI swede, this might come in handy, here we are talking about a generic term, like love, hate, etc.
3. Is the noun generic?
Generic reference is used when one refers to a whole group or class, to generalize about all possible members of a group. There are five patterns one can use:
a) no article PLUS plural count noun:
It's astonishing what gymnasts can do.
b) no article PLUS noncount noun:
Love can cause a lot of suffering.
c) indefinite article PLUS singular count noun:
It's astonishing what a gymnast can do.
[This pattern cannot be used to discuss the location or existence of
something/someone. You cannot say A lion lives in Africa. You
must use pattern (a) or (d)].
d) definite article PLUS singular count noun:
It's astonishing what the gymnast can do.
e) definite article PLUS plural nationality noun:
The Chinese have an ancient culture.
Pattern (a) is most common in colloquial English; pattern (d) is frequently used in academic writing.
