About parallelism

1. "Love of country is admirable, but today it is necessary to love humanity in general"

2. "America's founders were prepared to risk everything: their property, their reputations, and would even risk death"

3.""I agree with Hong Wei’s political views, but his way of expressing them is something I don’t agree with."

Hi, I read somewhere that when it comes to fomal writing, the two sentences above would be considered incorrect then because the last parts are not written in grammatically similar forms. And they should be more like the ones below

1."Love of country is admirable, but today love of humanity is necessary"

2."America's founders were prepared to risk everything: their property, their reputations, and even their lives."

3."I agree with Hong Wei’s political views, but I disagree with the way he expresses them."

My question is that is this grammatical similar form rules also applied for informal conversations?

Thank you
