It's interesting how any hint of this sentiment of 'catching' a man raises the ire of Marianne and Mrs. Dashwood--although Mrs. Dashwoo d is more diplomatic and polite in expressing her feelings on the topic.

I suppose the whole notion of treating falling in love like a 'conquest' or some sort of campaign offends their romantic sensibilities in the extreme.

Back in Ch. 4, Mrs. Dashwood felt contempt for Fanny and her insinuations that Elinor was trying to 'draw him in'. We also read in Ch. 3 that "it was contrary to every doctrine of [Mrs. Dashwood's], that difference of fortune should keep any couple asunder who were attracted by resemblance of disposition;"--and I suppose the corollary of that must be that it is equally contrary to Mrs. Dashwood's beliefs that people who were not attracted to each other in that way would be so mercenary as to pursue someone merely because he was a good 'catch'.
