Try and follow the argument.
Nothing in the entire section you quote invalidates what my comment said nor the original comment (in defence of which my comment was made).

Let me make easy for you:
1. a comment evoked the basic traditional Catholic teaching that we must ALWAYS follow our conscience
2. this was contested by a comment which quoted one para from the CC
3. I pointed out that this contestation was faulty, because the CCC itself acknowledges point 1
4. pointing out other paras (as you do) does not invalidate the force of the para that validates point 1
