[Stylistic aside: I don't know about other folks here, but to me, your employment of bold red italicized text to emphasize your key points is very akin to the "shouting" in all-upper-case letters that we all avoid as a matter of polite form. Any one of those three formatting enhancements would be sufficient to distinguish the emphasized text from its surroundings.
Though I suspect your combination of all three is simply an expression of how passionately you feel about the point being made, the effect (on this reader, at least) is to imply that your point doesn't stand on its own...]
while I agree with everything you have said, I did laugh when I noticed your signature!!
