My aren't we just a wee bit extra. Grammarly, as I'm sure you know. is void of emotions so there's no way it can "hate" a word.
Also, Grammarly makes suggestions. It's up to you whether or not you choose to use the option provided or not. Many times I've opted to leave my writing as is than to make certain recommended changes.
For those who don't have English as a first language or for those who have a limited education, Grammarly can be invaluable.
Even if you are strong in the English language Grammarly will still catch typos that you may have otherwise missed.
