First a small correction:
When you use the word point, you need the preposition from.
Here are some more phrases that can be used to give an opinion:
- In my view [size=92](not viewpoint!)[/size]
- To my way of thinking
- In my opinion
- As I see it
- It seems to me (that)
- I’d say (that)
- There’s no doubt in my mind (that)
- I’m absolutely convinced (that)
Of course, the last two phrases indicate a much stronger opinion than others. The others introduce an opinion in a more “neutral” way.
