Revolutionary terror in 1789 wasn't about killing the Bourgeisie- the French Revolution was a Bourgeois revolution- the Revolution was about overthrowing the Aristocracy, the nobles, the people with, as you say, titles- Being Bourgeois generally meant that you're common-born but well-educated and moneyed.

The fact that the Bourgeois of France were growing in real power, but completely unrepresented in the formal political systems in France, was one of the major pressure points that caused the entire system to explode into Revolutionary violence.

I think you're right to point out the irony that revolutionary violence mostly affected the common man, and not the aristocracy, but the "enemies of the revolution" were nobles, clergy, and their sympathizers (perceived or otherwise), not "the bourgeoisie".

Proletarian revolutions against the Bourgeois don't really happen until there IS an urban proletariat in the first place- in pre-industrial 1789, the bourgeois and the sans-culottes were grouped together socially in the "Third Estate".
