Alfredo,
Thanks for your question. I think in your question and narrative you have hit on the answer in part. Yes, the Deaf community is made up of individuals and these individuals vary in their experiences and opinions in the same ways that all populations vary. At an individual level I'm sure you will encounter Deaf people who are very open and welcoming to LGBT+ people. You will also run into individuals who react negatively.
In my experience the Deaf community and individuals who I have been associated with are open and welcoming to all members regardless of their sexual orientation and/or identity. Possibly you have hit on a reason for this; that is, the Deaf community is a minority community and culture within the larger population of hearing people and most Deaf people have faced discrimination in their daily lives. Given this they may be more prone to accept and welcome individuals who are different from themselves. A few examples, there is a Section of the National Association of the Deaf devoted to the LGBT+ Deaf community. See more information here: https://www.nad.org/members/sections/lgbt-section/
I would suggest that you search on the terms deaf and LGBT and you will uncover many resources and information that may deepen your perspective.
I trust my answer has steered you in the right direction to gain more insights.
