that i can read more about unbiased arguments for and against segwit and LN?
You should look for those separately. While one may have plenty more reasons to dislike LN, there is much less to do so with Segwit. There's actually a big page covering the problems/downsides of Segwit on the Bitcoin Core website:
Segregated Witness Costs and Risks, and here is the page covering the benefits
Segregated Witness Benefits. I think it's at least fairly unbiased considering how openly they addresses many of the potential problems.
If I am right, Andreas Antonopoulos supports the Segwit Softfork?
Yes. Listening to AA talk about Segwit may also be a great place to start.
