Remove trailing punctuation after standalone profanity with context-sensitive rules

[gylotip]

:loudspeaker: The Shortcoming

I do not want to see periods or commas when the filter removes a specific word; otherwise, I would know that profanity was used. I do not want to know if there is profanity used, so periods and commas should be removed in some cases, while in other cases, they should be preserved.

:microscope: Describe the solution you'd like

I want to figure out how to remove a comma or period that appears immediately after a specific word, but only under certain conditions. I do not want to remove it in all cases, but only when the word appears standalone, without being part of a larger phrase.

For example:

• Input: Crap. What should I do?
• Desired Output: What should I do?

In this case, the period after "Crap" is removed. However, I do not want this to happen if the word appears within a phrase before the punctuation.

For example:

• Input: Oh crap. What should I do?
• Desired Output: Oh. What should I do? (The period remains unchanged.)

The same logic should also apply to commas. However, if the removed punctuation was followed by a lowercase word, that word should be capitalized unless it was already at the start of the sentence.

For example:

• Input: Crap, this is confusing.
• Desired Output: This is confusing. (The comma is removed, and "this" is capitalized.)
• Input: Oh crap, this is confusing.
• Desired Output: Oh, this is confusing. (Since "crap" is part of a phrase, the comma is not removed.)

I want this logic to be applied effectively.

:triangular_ruler: Describe alternatives you've considered

I do not know of any solutions other than manually adding every single combination of periods and commas, along with profanity.
