Man,
In the ethical part I think you should think for yourself what is correct or not. Most people diets are not based in what is right or wrong, is just ancestral culture and we now as society are starting to think about it.
Socialy not everyone will accept that well and is not as practical as eating meat. But you can fine if you are sure about what you are doing. Some vegetarians/vegans are a lot of SJW intolerants to everyone non-vegan and that is not the way to go IMHO but some meat eaters are also too intolerant and that is not also the way to go and seem to have issues with vegans.
Related to health I go fine for 4 years vegan but you can have also a healthy diet eating meat.
If you want to go just see a doctor or nutricionist before to make sure you don't get deficiencies. If you make a bad nutrition and get anemic or something, you'll roll out and never come back.
In my case I got to a faculty nutricionist that told me what stuff I should add to my diet to not have problems.
Doctor told me most people going vegetarian/vegan that have health problems is because of bad information and going to the internet instead of consulting a specialist.
Cheers
