Replace `who is hating‘ by `who hates’.

The given sentence talks about two different terms, "philogynist" and "misogynist," which describe people's attitudes towards women. These terms are derived from the Greek words "philo," which means love, and "misos," which means hate. The suffix "-gynist" refers to a person who has a particular attitude towards women.

The sentence is structured as follows:

Subject - Verb - Object - Conjunction - Subject - Verb - Object

Here, the subject of the first part of the sentence is "a philogynist," and the verb is "is," which means "to be." The object is "a person." Similarly, the subject of the second part of the sentence is "a misogynist," and the verb is "is." The object is "a person" again. Both parts of the sentence are connected by the conjunction "but."

The error is in the fourth part of the sentence, where the verb "is hating" is used to describe the attitude of a misogynist towards women. This phrase is grammatically incorrect as the present continuous tense is not used to describe a state of mind or a habitual action. Instead, the simple present tense should be used to describe a person's attitude or belief.

Therefore, the correct form of the sentence should be:

"A philogynist is a person who loves women, but a misogynist is a person who hates women."

To summarize, the error in the given sentence is the incorrect usage of the present continuous tense in part (4). The correct sentence should use the simple present tense to describe a person's attitude or belief towards women.
