I wouldn't say that's totally true.
很多人在表達否定觀點的時候,都會用"I don't think…",比如這一句就可以說"I don't think that's totally true."但是如果用"I wouldn't say",語氣明顯緩和了下來,而且對話兩人很可能是好友的關系,在平時閑聊的時候,語氣最好不要顯得那樣生硬.

這里的left girl,就是指現在很流行的"剩女"這個詞了吧.
You have a point here, but I believe some mixed marriages are based on true love.
you have a point here是很地道的表達法,意思是"不錯,你的話有理,你說的有道理".
